摘要
红外测温技术由于方便、快速、准确而被广泛应用于航空、医学等很多领域。介绍了一种非接触式测温方案,采用MLX90615红外温度传感器和MSP430F149单片机来实现。单片机通过SMbus方式与MLX90615进行通信,将读出的温度数据进行处理,之后驱动LCD模块显示测量温度。发射率可根据测量目标进行设置,用以提高测温仪的测量精度。
Infrared temperature measurement technology is widely used in aviation, medical and many other fields because it is convenient, rapid and accurate. A kind of non-contact thermometric program is introduced, infrared temperature sensor MLXg0615 and single chip MSP430F149 are applied to achieve the functions. Single chip communicates with MLXg0615 by means of SMbus, and the temperature datas read from the sensor are processed. The LCD module is driven to display the tested temperature. The emissivity can be set according to different measured objects to improve measurement precision.
