7Semi MLX90640 55 FOV Thermal Camera IR Array Breakout Qwiic Compatible

The 7Semi MLX90640 Thermal Imaging Camera Module is a compact infrared thermal sensor solution designed for accurate, non-contact temperature measurement and thermal imaging applications. Based on the Melexis MLX90640 sensor, the module incorporates a 32 × 24 pixel thermal array capable of capturing 768 independent temperature points in real time.

The module features a 55° × 35° field of view, making it suitable for monitoring larger scenes while maintaining detailed thermal information. Temperature data is accessed through a standard I²C interface, enabling straightforward integration with Arduino, ESP32, STM32, Raspberry Pi, and other embedded platforms.

The MLX90640 includes factory calibration data, an integrated ambient temperature sensor, and supply voltage monitoring. Programmable refresh rates from 0.5 Hz to 64 Hz allow developers to optimize between low-power operation and higher frame-rate thermal imaging. With support for Python, C++, and numerous open-source libraries, the module can be rapidly integrated into industrial, research, educational, and IoT applications.
