1、前言

数字温度计是测温仪器类型的其中之一。根据所用测温物质的不同和测温范围的不同，有煤油温度计、酒精温度计、水银温度计、气体温度计、电阻温度计、温差电偶温度计、辐射温度计和光测温度计、双金属温度计等。
2、方案概述

Ameya360 数字温度计解决方案与传统的温度计相比，具有读数方便，测温范围广，测温准确，其输出温度采用数字显示，主要用于对测温比较准确的场所，或科研实验室使用。它具有结构简单, 不需外接元件, 采用一根 I/ O 数据线既可供电又可传输数据、并可由用户设置温度报警界限等特点, 可广泛用于食品库、冷库、粮库等需要控制温度的地方。该设计控制器使用单片机、测温传感器实现温度显示。还有 A/D 转换和译码器两部分构成，可以直接驱动数码管，省去了译码器的接线，在硬件电路焊接上，只需要少量外部元件就可以精确测量 0 到 200mv 电压，温度采集传感器本身输出转换电压与输入非电量温度之间成线性关系。所以该电路核心是用驱动数码管实现信号的显示。
