Intelligent Temperature Measurement and Access Control System

Aiming at the problem of long queuing temperature and low efficiency during the period of COVID-19, an intelligent temperature measurement and access control system is designed. It is widely used in enterprises, institutions, scenic spots, commercial areas and other places with large traffic volume. The main control system adopts stm32f407zgt6 embedded chip, hc-sr501 human body infrared sensor is sensitive to human body proximity, and starts the temperature measurement system. Using hc-sr04 ultrasonic sensor to measure people’s height and adjust the height of mlx9064esf temperature probe, the system has the characteristics of efficient real-time temperature monitoring, and improves the detection efficiency in places with large flow of people. The experimental results show that the system has good practical application effect.
