基于STM32的非接触式红外体温检测系统设计
Design of Non-contact Infrared Body Temperature Detection System Based on STM32
摘要
Abstract
Body temperature is an important physiological indicator of the human body,and body temperature detection is a basic means for screening human health status.During the pandemic of infectious diseases,efficient and rapid non-contact body temperature detection is particularly important.Based on the STM32 main control chip,a non-contact infrared body temperature detection system is designed using an infrared sensor MLX90614 and an ultrasonic sensor HC-SR04.It controls the distance of the target to be tested through HC-SR04,collects surface temperature data of the target through MLX90614,processes and converts it by the microprocessor,and outputs it by the interaction module.When the target distance exceeds the optimal range or the target temperature exceeds the set healthy temperature threshold,the buzzer will sound an alarm prompt.Through comparative testing with traditional mercury thermometers and commercial infrared thermometers,it has been verified that the designed system can quickly and accurately detect human body temperature.关键词
