MLX90640 IR Array Thermal Imaging Camera, 32×24 Pixels, 110° Field of View, I2C Interface

Overview

This is a 32×24 pixels, 110° field of view, IR array thermal imaging camera, communicating via I2C interface. It is compatible with 3.3V/5V operating voltage, supports host platforms such as Raspberry Pi/Arduino(ESP32)/STM32, etc.

By utilizing the MLX90640 far-infrared thermal sensor array, this module can detect the IR distribution of objects in the field of view, turn the data into surface temperature of the objects by calculation, and then generate thermal images. Due to the small form factor, it can be easily integrated into miscellaneous industrial or intelligent control applications.
