Abstract: A kind of pyroelectric infrared temperature measurement system was designed, which core was the ATmage32 SCM. It was a non-contact and voice prompt temperature measurement system by using pyroelectric infrared sensor. It used the pyroelectric infrared sensor to extrat the temperature of the human body and the DS18B20 to measure the environmental temperature, which could achieve the temperature compensation to reduce the measurement error. It could be controlled to realize the temperature convertion and processing, and sent the temperature value to the LCD to display and the voice prompt by the AVR SCM. Simultaneously, it was added the clock function and overtemperature alarm function to make the design more practical. The temperature measurement range was from 35-42℃. The measurement time was less than 1s. The temperature measurement system had the advantages of handy use, good flexibility, high reliability, and had a promotional value.
