【Abstract】 Physical characteristics of a kind of pyroelectric sensor was measured in this paper. The influence of environmental factors on the measurement results were studied,such as the distance between the sensor and the object,the speed of the object,laboratory temperature and humidity.On this basis,a contactless temperature measuring device was made by ourselves,which can be used to monitor the body temperature of moving people in real-time.更多还原
