摘　　要：金属热电阻是一种广泛应用的温度传感器,其中铂电阻传感器被定为测温的基准。现采用ATmega16单片机作为核心处理器,用Pt100热电阻作为温度采集的传感器,设计一种便携式数字温度计。文中较为详细地介绍了该温度计的组成结构、工作原理、硬件构成及软件设计。该温度计试验运行良好,精确度高、携带方便、成本低廉、反应速度快,可靠性高,具有广阔的应用和推广前景。Metal thermal resistance is a kind of widely used temperature sensor,and platinum resistor is usually set for the criterion in temperature measuring. Based on ATmegal6 single chip microcompater as the core processor and Pt100 thermal resistance as the temperature sensor, a portable digital thermometer is designed. In this paper, the thermometer structure and working principle are described in detail and the design of relevant hardware and software is given out. The thermometer runs well in the test, and it has high liability, high precision,low cost,high response speed, and convenience to carry, which has a bright prospect of appiication and popularization.
