Exploring Infrared Sensors: Types, Applications, and Principle

　　In the realm of modern technology, infrared (IR) sensors stand out as versatile and essential components across a wide array of applications. These sensors leverage the infrared part of the electromagnetic spectrum to detect and measure infrared radiation, which can be indicative of heat, motion, and various other parameters. This article delves into the fundamentals of Infrared Sensors, and their diverse applications.　　What is an infrared sensor ?Infrared sensors detect radiation in the infrared spectrum, which ranges from about 750 nanometers (nm) to 1 millimeter (mm). Unlike visible light, infrared radiation is not visible to the human eye but can be felt as heat. IR sensors convert this radiation into an electrical signal that can be processed and interpreted by electronic systems.　　How many types of IR sensors are there?1. Active Infrared Sensors: These sensors emit their own infrared light and detect the reflected light. They are commonly used in proximity sensors and certain types of motion detectors. An example is the IR LED and photodiode pair, which measures changes in the reflected light to determine the presence of objects.　　2. Passive Infrared Sensors (PIR): Unlike active sensors, PIR sensors do not emit any radiation. Instead, they detect the infrared radiation naturally emitted by objects. PIR sensors are widely used in motion detection applications, such as security systems and automatic lighting.　　What is the purpose of the IR sensor?IR sensors serve various purposes across multiple applications. Here are some common uses:　　1. Proximity Detection　　– Used in devices like automatic doors, smartphones, and vehicles to detect nearby objects without physical contact.　　2. Motion Detection　　– Common in security systems and alarms (e.g., PIR sensors) to sense movement in a defined area.　　3. Temperature Measurement　　– Employed in non-contact thermometers to measure the temperature of objects or bodies from a distance.　　4. Remote Controls　　– Found in TVs, air conditioners, and other electronics to facilitate wireless communication with remote controls.　　5. Obstacle Avoidance　　– Used in robotics and drones to navigate and avoid collisions by detecting nearby objects.　　6. Gas Detection　　– Some IR sensors can detect specific gases based on their absorption of infrared light, useful in industrial applications.　　7. Night Vision and Thermal Imaging　　– Used in military, security, and surveillance applications to detect heat signatures in low-light conditions.　　8. Data Transmission　　– In certain applications, IR can be used for wireless data transfer over short distances.　　What is an infrared sensor used for?Infrared sensors have a broad range of applications, benefiting various industries from consumer electronics to healthcare. Here are some notable examples:　　1. Consumer Electronics:　　– Remote Controls: IR sensors are integral to remote control devices for televisions, air conditioners, and other home appliances. They receive signals from the remote control unit to perform the desired function.　　– Smartphones and Tablets: Some devices use IR sensors for facial recognition, which helps in unlocking screens and enhancing security.　　2. Healthcare:　　– Thermography: Infrared thermography is used for non-invasive temperature measurement, allowing for early detection of fevers and other medical conditions. It’s particularly valuable in monitoring patients’ health and in diagnosing conditions based on temperature anomalies.　　– Vital Sign Monitoring: IR sensors can be used in wearable devices to monitor vital signs such as heart rate and blood oxygen levels.　　3. Automotive Industry:　　– Collision Avoidance Systems: IR sensors help in detecting obstacles and monitoring the surrounding environment to prevent accidents. They are used in parking assist systems and adaptive cruise control.　　– Night Vision: Some high-end vehicles are equipped with IR sensors to enhance visibility during night driving by detecting pedestrians and animals on the road.　　4. Industrial Automation:　　– Temperature Measurement: In manufacturing processes, IR sensors are employed to monitor the temperature of machinery and products to ensure they remain within safe and optimal limits.　　– Quality Control: These sensors are used to inspect products for defects and irregularities by detecting variations in thermal emission.　　5. Environmental Monitoring:　　– Gas Detection: IR sensors can detect the presence and concentration of specific gases in the atmosphere by measuring their absorption of infrared light. This is crucial for monitoring air quality and ensuring safety in industrial environments.　　What is the principle of IR sensor?The principle of an infrared (IR) sensor is based on the detection and measurement of infrared radiation, which is electromagnetic radiation with wavelengths longer than visible light. The core principle involves capturing the infrared radiation emitted or reflected by objects and converting it into an electrical signal that can be analyzed. Here’s a detailed breakdown of how IR sensors work:　　1. Emission and Detection of Infrared Radiation　　Infrared Radiation Basics:　　– Infrared radiation is part of the electromagnetic spectrum with wavelengths ranging from approximately 750 nanometers (nm) to 1 millimeter (mm), just beyond the visible light spectrum.　　– All objects emit infrared radiation as a function of their temperature. Hotter objects emit more infrared radiation compared to cooler ones.　　Detection Principle:　　– Active IR Sensors: These sensors emit their own infrared light (often using an IR LED) and then measure the amount of this light that is reflected back from objects in their environment. The detected signal changes based on the distance, size, and properties of the object, allowing the sensor to infer its presence, distance, or other characteristics.　　– Passive IR Sensors (PIR): These sensors do not emit any radiation. Instead, they detect the infrared radiation naturally emitted by objects in their field of view. They typically use a sensor element that responds to changes in infrared radiation, such as a pyroelectric detector or a thermopile.　　2. Conversion of Infrared Radiation to Electrical Signal　　Pyroelectric Detectors:　　– Pyroelectric sensors contain materials that generate an electrical charge when exposed to infrared radiation. This charge is proportional to the amount of infrared radiation detected.　　– The sensor detects changes in temperature caused by infrared radiation, converting these changes into an electrical signal.　　Thermopiles:　　– A thermopile consists of multiple thermocouples connected in series or parallel. It measures the temperature difference between the heated element exposed to infrared radiation and a reference element.　　– This temperature difference generates a voltage, which is then measured and converted into an output signal.　　Photodetectors:　　– Some IR sensors use photodetectors (such as photodiodes or phototransistors) sensitive to infrared light. These detectors convert the incident infrared light into an electrical current proportional to the light intensity.　　3. Signal Processing　　Once the infrared radiation is converted into an electrical signal, the output is typically processed and analyzed by the sensor’s electronics. This may involve amplification, filtering, and digitization of the signal. The processed signal can then be used to trigger actions or provide readings depending on the application. For example:　　– In motion detectors, the sensor might trigger an alarm if it detects significant changes in infrared radiation indicating movement.　　– In temperature measurement systems, the signal is used to provide accurate temperature readings or to monitor thermal conditions.　　How do I choose an IR sensor?Choosing an infrared (IR) sensor depends on several factors related to your application. Here’s a quick guide to help you make the right choice:　　1. Type of IR Sensor　　– Active IR Sensors: Emit IR light and measure reflections (e.g., proximity sensors).　　– Passive IR Sensors: Detect IR radiation from objects (e.g., PIR sensors for motion detection).　　2. Detection Range　　– Consider the distance over which you need to detect objects. Check the specifications for range and field of view.　　3. Sensitivity　　– Look for specifications on sensitivity, which determines how small a change in IR radiation the sensor can detect.　　4. Environmental Conditions　　– Ensure the sensor can operate in the conditions it will face (temperature, humidity, dust, etc.).　　5. Response Time　　– Consider how quickly the sensor needs to respond. This is crucial for applications like motion detection.　　6. Output Type　　– Decide whether you need digital output (on/off) or analog output (variable signal) based on how you’ll process the sensor data.　　7. Power Consumption　　– Look for power-efficient models if you’re running on batteries or need to minimize energy use.　　8. Size and Form Factor　　– Ensure the physical size and mounting options fit your project requirements.　　9. Cost　　– Determine your budget, as prices can vary widely based on features and capabilities.　　10. Manufacturer Support　　– Choose brands or suppliers that provide good documentation and support.　　How far can IR sensors detect?The detection range of IR sensors can vary significantly based on the type of sensor and its design:　　1. Active IR Sensors　　– Proximity Sensors: Typically have a range of a few centimeters to a few meters (around 0.1 to 5 meters) depending on the sensor’s power and environment.　　– IR Range Finders: Can detect distances up to 10-20 meters or more, depending on the model and application.　　2. Passive IR Sensors (PIR)　　– Commonly used for motion detection in security systems, these sensors usually have a range of about 5 to 12 meters (16 to 40 feet). The actual range can be influenced by factors such as the angle of detection and the presence of obstacles.　　3. IR Cameras and Thermal Sensors　　– These devices can detect heat signatures at much greater distances, often exceeding 100 meters, depending on the resolution and the environment.　　Factors Influencing Range　　– Sensitivity: Higher sensitivity allows for detection at greater distances.　　– Environmental Conditions: Obstructions, temperature, and humidity can affect performance.　　– Field of View: A wider field of view may reduce the effective detection range.　　ConclusionInfrared sensors are indispensable components in modern technology, offering critical functionalities across various fields. From enhancing consumer electronics to advancing healthcare and industrial automation, their applications are both diverse and impactful.

Temperature Sensor : Types, Applications, Working Principle and Much More

　　A temperature sensor is a vital component in many systems where monitoring or controlling of temperature is required.　　It allows one to measure the temperature of an object or environment and provide thermal data which is further used by various devices and applications.　　Temperature sensors play an important role across many industries from automotive and medical to consumer appliances.　　What is a temperature sensor?A temperature sensor is a device that helps in measuring the temperature of its environment, object or substance and converts the measurement into an electronic signal.　　This electronic signal is further processed by auxiliary instrumentation such as temperature indicators, temperature controllers and temperature recorders to display or use the temperature data.　　There are various types of temperature sensors available based on different sensing technologies like thermistor, thermocouple, Resistance Temperature Detector (RTD) etc.　　What are different types of temperature sensors?Some of the common types of temperature sensors are:　　Thermocouple　　A thermocouple is a temperature sensor made by joining two different conductors at their ends to form a thermocouple junction. The voltage produced is dependent on the temperature difference between the thermocouple junction and a reference junction. Thermocouples are inexpensive, rugged and can measure a wide range of temperatures.　　Resistance Temperature Detector (RTD)　　An RTD is made up of a pure metal like platinum, copper or nickel which exhibits change in electrical resistance when exposed to change in temperature. The resistance increases linearly as temperature rises which makes it easy to convert to temperature using a simple formula. RTDs provide good accuracy over a wide temperature range.　　Thermistor　　A thermistor is a type of resistor whose resistance varies significantly with temperature changes. It exhibits a non-linear but known resistance-to-temperature relationship. Negative temperature coefficient (NTC) thermistors decrease in resistance with rising temperature while positive temperature coefficient (PTC) thermistors increase in resistance. They provide high accuracy and fast response time.　　Integrated Circuit Sensor　　An integrated circuit temperature sensor consists of a temperature sensitive circuit integrated onto a silicon chip that outputs voltage proportional to sensed temperature. They are small in size, inexpensive and mass producible. But accuracy is less as compared to other sensor types.　　Infrared Sensor　　Infrared sensors detect infrared energy radiated from an object or surface and produce an electronic signal proportional to the temperature. They are contactless and suitable to measure temperature without disturbing the environment but have less accuracy.　　What are the advantages and disadvantages of temperature sensors?Advantages　　• Provide accurate and repeatable temperature measurements.　　• Respond quickly to temperature variations.　　• Can measure a wide range of temperatures from below zero to thousands of degrees Celsius depending on type.　　• Rugged, withstand vibrations and withstand hostile environmental conditions like humidity and pressure.　　• Low cost options available for general purpose temperature measurements.　　• Integrated circuit temperature sensors are small, mass producible and inexpensive.　　Disadvantages　　• Contact sensors disturb the medium whose temperature is being measured.　　• Thermocouples produce small voltage signals requiring amplification.　　• Response time of temperature sensors depends on thermal mass and insulation which limits fast temperature tracking.　　• Temperature sensors have limited lifespan and require calibration over time.　　• Special sensors are needed for measuring ultra-low or ultra-high temperatures.　　How important is a temperature sensor?　　A temperature sensor plays a vital role in maintaining quality and safety standards across many industries.　　Some key applications where temperature sensors are mission critical include:　　• Medical equipment and patient monitoring – Ensures safe temperatures for drug infusion, surgical/therapy devices, incubators etc.　　• Automotive – Monitors engine temperature, fuel systems, brake fluid, transmission oil, exhaust gas recirculation.　　• Industrial manufacturing – Controls processes in plastics molding, food processing, chemical reactions requiring specific temperatures.　　• HVAC equipment – Essential component in thermostats, air conditioners, refrigerators to regulate temperatures.　　• Fire/overheat detection – Prevents accidents by triggering alarms when abnormal high temperatures detected.　　• Consumer appliances – Maintains safe cooking temperatures in ovens/stoves, cool temperatures in refrigerators.　　Where are temperature sensors used?Industrial applications　　Oil and gas plants to monitor pipeline temperatures, boiler temperatures.　　Pulp and paper industry for dryer skin temperatures, consistency measurements.　　Power plants to monitor transformer temperatures, boiler steam temperatures.　　Iron and steel industry for molten metal temperatures, annealing furnace controls.　　Automotive　　Engine coolant temperature sensor in radiator.　　Intake air temperature sensor.　　Exhaust gas temperature sensor before catalytic converter.　　Transmission fluid temperature sensor.　　Rear differential and transfer case temperature sensors.　　Medical　　Patient thermoregulation- temperature probes in incubators, warming blankets.　　Medical sterilizers- monitors autoclave temperatures.　　Hyperthermia therapy- controls localized temperature increases.　　HVAC　　Thermostat temperature sensor　　Duct-mounted temperature sensors　　Outdoor temperature sensors　　Household appliances　　Refrigerator/freezer temperature sensors　　Oven temperature sensors　　Water heater thermostats　　What is the difference between thermal sensor and temperature sensor?The main difference between a thermal sensor and a temperature sensor are:　　Thermal sensors detect heat without direct contact while temperature sensors measure temperature through properties like resistance that change with temperature.　　Thermal sensors provide relative heat indication without units while temperature sensors provide measured temperature output in units like Celsius or Fahrenheit.　　How do temperature sensors work?Temperature sensors function based on different working principles depending on the sensing technology used:　　Thermistors　　Thermistors are made from semiconductor materials that change resistance predictably with temperature changes. As temperature rises, the mobility of charge carriers in the semiconductor increases resulting in lower electrical resistance that can be measured.　　Thermocouples　　When two different conductors are joined together, a voltage is produced dependent on their Seebeck coefficient and the temperature difference between the junction and reference junction. The output voltage is linearly proportional to temperature and is measured.　　RTDs　　Resistance Temperature Detectors use metals like platinum that change resistance reliably with temperature. Resistance increases linearly as temperature rises following PRT (Platinum Resistance Thermometers) or ITS-90 standard curves.　　Integrated circuits　　Complementary metal–oxide–semiconductors (CMOS) and bipolar transistors on an IC change current or voltage levels proportionally to temperature which is output analog or digital signals.　　Infrared sensors　　Infrared sensors contain a detector which absorbs infrared radiation from the target. The absorbed IR energy causes the detector temperature to rise above ambient. This temperature change alters the electrical properties to provide an output signal related to target temperature.　　How to design a temperature sensor?　　The steps involved in designing a temperature sensor are:　　1. Select sensing element material based on required temperature range, accuracy, response time etc. like RTD, thermistor etc.　　2. Design sensor probe matching application requirements like immersion, surface, air temperature sensing.　　3. Choose appropriate housing material that withstands application environment. Consider thermal insulation, heat transfer etc.　　4. Design signal conditioning circuitry to convert sensor output to standardized signals compatible with instruments like amplifiers, filters, transmitters etc.　　5. Develop calibration curves and apply compensation algorithms in microcontroller if required for high accuracy.　　6. Implement temperature scaling and linearization if needed in firmware or hardware.　　7. Add optional features like remote sensor with transmission line, displays, alarms, microprocessor integration.　　8. Test prototype under standard reference temperatures for calibration, accuracy, repeatability.　　9. Enhance product through validation testing under field conditions, certifications.　　10. Prepare design documentation for manufacturing.　　What is the range of a temperature sensor?Temperature sensors can measure a wide range of temperatures based on the sensing technology and construction. Some common measurement ranges are:　　• Thermocouples: -250°C to 1350°C　　• RTDs: -200°C to 650°C　　• Thermistors: -55°C to 150°C　　• Integrated circuits: -55°C to 150°C　　• Infrared sensors: -50°C to 500°C　　Special types of sensors further extend the limits to measure very low cryogenic temperatures below -200°C for applications like liquified natural gas plants, high energy physics labs.　　Similarly, special metallurgical thermocouples and optical pyrometer sensors go up to 3000°C for processes like steel making, glass welding.　　ConclusionAn accurate and reliable temperature sensor is fundamental for process and quality control across major industries due to its role in monitoring, regulating and safety applications.　　Understanding sensor types, principles, design and selection based on application demands is key.　　Advancing technologies are continuously improving sensing capabilities to wider ranges, higher precisions and intelligent outputs.　　As temperature measurement takes a more vital role, evolution of sensors will keep pace with the emerging trends.

NOVOSENSE launches automotive-grade temperature and humidity sensor NSHT30-Q1, driving the development of automotive intelligence

　　NOVOSENSE's new automotive temperature and humidity sensor NSHT30-Q1 is a relative humidity (RH) and temperature sensor based on CMOS-MEMS.　　NSHT30-Q1 integrates a complete sensor system on a single chip, including a capacitive RH sensor, CMOS temperature sensor and signal processor, and an I2C digital communication interface. It is designed in DFN package with Wettable Flank, and the product size is only 2.5mm×2.5mm×0.9mm. The I2C interface communication mode, small and reliable package, and wider operating temperature range make NSHT30-Q1 well suited for automotive applications.　　With the development of automotive intelligence, in-vehicle systems increasingly rely on judgment of the surrounding environment to make decisions. To achieve real-time control and autonomous operation, these systems need to capture necessary information with high-precision sensor products that can respond quickly.　　Take the automotive 5-in-1 sensor as an example. It uses the built-in temperature and humidity sensor to detect the temperature and humidity on the inside of the front windshield, and then calculates the dew point temperature. In this way, the air conditioning system can adjust the temperature inside the vehicle, the air outlet mode, the internal and external circulation, and other functions according to these signals, effectively reducing the humidity inside the vehicle and achieving the defogging function.　　At the same time, the lidar cannot work without support from the temperature and humidity sensor.

novosns：Sensors improve the energy efficiency and environmental performance of central air conditioners through precise temperature, humidity, pressure, and current measurement

　　With the improvement in people's living standards and the growing demand for a more comfortable living environment, China's central air conditioning market has maintained relatively stable growth. Temperature and humidity, pressure, and current sensors with high-precision detection capability are critical to the various functions of central air conditioning. As a manufacturer of high-performance, high-reliability analog and mixed-signal chips, NOVOSENSE offers a wide range of sensor and analog IC solutions for central air conditioning applications.　　Development trends and new requirements for central air conditioning　　According to statistics, in the first half of 2023, in China's central air conditioning sales, multi-connected systems accounted for approximately 51%, continuing to rank first in the market. The reason why multi-connected systems are favored by the market mainly lies in their low installation cost, flexible applications, and high energy efficiency. For this reason, some well-decorated homes have also begun to standardize on this type of air conditioning.　　Commercial central air conditioners adopt a one-to-many architecture, in which an outdoor unit drives multiple indoor units. Each indoor unit has a corresponding line controller, which can automatically adjust the air outlet, airflow, and cooling and heating power through the feedback of temperature and humidity to maintain a comfortable indoor temperature.　　The development trend of multi-connection technology is mainly reflected in two directions. One is energy saving and noise reduction: outdoor units and even indoor units have frequency conversion capabilities, which can reduce noise by increasing the frequency while achieving low standby power consumption. The other is better comfort and improved environmental performance: meeting specific requirements for airflow, temperature and humidity control while reducing the damage of refrigerant leakage to the natural environment to ensure effective air conditioning.　　· NOVOSENSE's sensor products can exactly meet the above trend requirements. These products include temperature and humidity sensors and pressure sensors that meet comfort and environmental performance requirements, magnetic current sensors that ensure normal operation of outdoor units, and various analog IC products.　　NOVOSENSE offers comprehensive sensor solutions for central air conditioning applications　　The temperature and humidity sensor is used to detect the ambient temperature and humidity to control the airflow from the air outlet and balance the ambient humidity for improved comfort.　　NSHT30 is a temperature and humidity sensor with very small size and very high accuracy. It adopts a 2.5mm×2.5mm small package (LGA and DFN options). The MCU reads the temperature and humidity data through the I²C interface of the sensor. Temperature and humidity measurements are from -40°C to 125°C and from 0 to 100%, which can basically cover all temperature and humidity ranges.　　The advantage of NSHT30 is, first of all, the response time. The acquisition time of temperature and humidity is only 2s and 6s, respectively. Its accuracy is also higher than other similar products in the market. The chip calibration before leaving the factory can ensure high accuracy requirements. Under the condition of 0~50°C, the error of NSHT30 can be controlled at ±0.3°C (typical value); and under the condition of 50% relative humidity, the error can be controlled at ±3% to meet the accuracy requirements of air conditioning.　　The pressure sensor is usually placed on the outdoor unit or refrigerant transmission pipe to detect refrigerant leakage and refrigerant pressure, ensuring effective air conditioning while achieving environmental performance.　　NSPAS3 is an integrated absolute pressure sensor for refrigerant leakage pressure detection in air conditioners. Its operating temperature is from -40°C to 130°C, and its internally integrated temperature compensation circuit can achieve ±1% control accuracy in the range of 0~85°C and ±1.5% control accuracy in the range of -40°C to full temperature.　　NSPAS3 is compatible with the pressure test range of 10kPa~400kPa and can detect refrigerant leakage pressure. The standby power consumption of this product is less than 3mA, and the response time is within 0.8ms. In addition, the chip package is coated with anti-corrosion jelly glue, which can prevent some corrosive gases from damaging the chip package.　　NSC2860x is a capacitive pressure transmitter signal processing ASIC solution. It can detect the refrigerant pressure (3~5MPa) in the air conditioning compressor. The chip integrates various digital components such as PGA, ADC, MCU and various interfaces. It has a very high degree of integration and can convert the monitored pressure into a digital signal for processing by the MCU. NSC2860x also integrates a 4-20mA loop power supply, which enables longer distance transmission to meet the communication distance requirements between the pressure sensor and the MCU main control board in the refrigerant system.　　The magnetic current sensor is generally placed in the outdoor unit and is mainly used to monitor the current of the outdoor unit, such as PFC current or phase current of the air conditioning compressor motor. It achieves tracking feedback by collecting system current signals to ensure normal operation of the system.　　NSM2019 is an integrated Hall current sensor, mainly used to detect the motor current or PFC current of the air conditioner. The MCU reads the current value through the VOUT pin. It integrates the reference voltage and OCP (overcurrent protection) internally, eliminating the need for some peripheral devices such as comparators or op amplifiers. This product covers a range of 20A~200A, which can meet the power requirements of commercial air conditioners from several kilowatts to one hundred kilowatts.　　NSM2019 has an accuracy of ±2% and can guarantee accuracy over the full temperature range. Its isolation withstand voltage is up to 5,000V, the creepage distance is up to 8.2mm, and it can withstand 20kA surge current. Its input bandwidth is as high as 320K, which can meet the bandwidth requirements of current detection. Due to the small internal resistance, the heat output of the chip is also small.　　Other analog IC solutions for central air conditioning applications　　In addition to sensors, NOVOSENSE offers many analog IC product solutions. Analog ICs are mostly used in outdoor units. The topology of the outdoor unit determines that the 220V mains power needs to be rectified by PFC to approximately 400VDC, which then feeds the bus voltage of the two motors. The motor is directly driven by IGBT or IPM. The MCU that drives the IGBT is usually placed at the low voltage end, so it is necessary to use an isolated driver to rotate the motor. As a result, many isolated driver products are required. At the same time, the current and voltage must be monitored. The PLC also needs to collect the voltage and current, so op amplifier products are also used.　　The outdoor unit and the indoor unit communicate through 485 or CAN bus. Since the two generally do not share a common ground, some isolated interfaces are also needed. NOVOSENSE provides digital isolator products that convert high voltage to low voltage to power MCUs. The power supply is usually converted from high voltage to low voltage by flyback power supply, then converted to 5V by DC-DC, and then converted to 3.3V by LDO to power other chips.
