This thermal camera measures temperature and displays the thermal imaging figure. It is based on MLX90640, a 32x24 array thermal sensor (MLX90640), detects the temperature of objects from feet away with the accuracy of ±1.5℃.

The FOV(Field of View) of this camera is 55°x35°, and the temperature measurement range is -40℃~300℃. It communicates with the controller with the I2C interface. Please check our demos of usage with ESP32-S3 parallel TFT Touch:
