Non-contact Infrared Temperature Measuring Device based on stm32

Abstract

With the epidemic raging around the world, people's health is under great threat. How people can detect the epidemic in the first time becomes a very important matter. At this stage, the primary symptom of the outbreak is fever. Therefore, whether in hospitals, various government administrative departments or in office buildings, residential areas and other crowded areas, will be measured by the body temperature to judge the health of personnel. However, the traditional methods of temperature detection need to touch or test the subjects at close range, which will bring certain threats to the human health of the inspectors. Therefore, the design of non-contact and remote epidemic prevention and control equipment is extremely urgent. In this paper, through the use of STM32F103C8T6 micro-controller, the ultrasonic ranging module is used to monitor the distance of the measured personnel in real time. When the measured personnel enter the test range, the infrared temperature sensor MLX90614 is used to test the temperature of the measured personnel. Once it exceeds the set alarm value, the alarm is alerted. The system has high testing efficiency and precision, which is suitable for epidemic prevention and control.
