Research and Design of Simple Non-contact Temperature Measurement and Identification Device

With the advent of the post-epidemic era, more and more people realize the importance of working without contact. This paper designs a simple non-contact temperature measurement and identification device, which has application value in public places such as rail transit station and campus community. This design device takes STM32F103 and STM32F407 chips as the core processors, supplemented by related peripheral circuits, to conduct contactless temperature measurement and identification. It combines contactless temperature measurement and face recognition technology, which can achieve contactless temperature measurement, threshold adjustment, face recognition, beyond the threshold can automatically alarm and other functions. Compared with the current fixed identification device in the station, this design has the advantages of mobile, portable, complete information collection, high intelligence, and wide range of applicable scenarios.
