业领域走进了医疗领域和日常生活。用传统的温度计测量温度的缺点非常明显，尤其是其需要测量者与被测目标近距离接触，这不仅会带来测量的不便和较大的误差，在很多情况下还会影响测量者的平安。
在查阅了大量国内外文献的根底上，提出了一种以单片机为核心，进展软硬件设计，对信号进展处理，其外接红外测温模块、键盘显示、电源模块、A/D转换模块等，能实现对温度的采集、计算与显示。
基于单片机的红外测温仪主要由光学系统、探测单元和信号处理三局部共同组成的。光学测量系统对象的主要作用是收集辐射功率，并允许红外探测器收集。红外探测器的作用是将接收到的红外辐射转换为电信号输出。电信号处理局部的作用主要是对探测的微弱信号进展放大, 以到达显示或记录被测温度的目的。为了使红外线测温仪，具有高的信号输出，它应该需要高灵敏度的检测器，一个低噪声的信号处理仪器系统。为了精细红外测温仪高发射率的调整，提出温度补偿，准确的温度校正措施。

Abstract
As the main method for non-contact measurement, infrared measurement has many advantages, such as fast response, wide measuring range, high sensitivity, and so on. It can be used in various spots. When infrared thermometer, and uses non-contact method of measuring temperature in medicine to regulate the infrared thermometer, ranging from ℃ to ℃accuracy should be ℃, which is used in medicine. But the thermometer Infrared can not achieve this regulation. Meanwhile the accuracy of the thermometer in the infrared this temperature range can be significantly affected by the error temperature of the surrounding environment also increased significantly.
After the search of large amounts of data, and disadvantages of infrared thermometer group medical, and a new way to compensate for the ambient temperature, and the principle of detecting electrical heat on the basis of this new way of paper. This proposed and determine the amount of compensation according to the temperature is measured at the difference between goals and ambient temperature surrounding. The programs address the dig
