Aiming at the problems of low resolution and limited monitoring range of traditional infrared sensors,a high-resolution temperature monitoring system based on MLX90640 infrared sensor is built in this paper.The system uses STM32F401RCT6 as the core controller and MLX90640 as the temperature sensor.The controller communicates with the MLX90640 through the I2C bus, and transmits the temperature data to the host computer software through the UART interface.The software can display the infrared thermal image of the measured target temperature in real time.Experiments show that the non-contact temp...
