Adafruit MLX90640 IR Thermal Camera Breakout

You can now add affordable heat vision to your project with an Adafruit MLX90640 Thermal Camera Breakout. This sensor contains a 24x32 array of IR thermal sensors, providing a compact yet high-performing solution for infrared temperature readings.

When connected to your microcontroller or Raspberry Pi, it returns an array of 768 individual temperature readings over I2C, effectively transforming your setup into a mini thermal imaging device. It's as simple as integrating a compact thermal camera, perfect for innovations like human detectors.

This version features a narrow 55°x35° field of view, with an alternative wider 110°x70° version available. The sensor measures temperatures from -40°C to 300°C, maintaining an accuracy of ±2°C between 0-100°C. Its maximum frame rate is 16 Hz, providing smooth thermal video for most applications.

To facilitate integration, we’ve equipped it with a 3.3V regulator and level shifting on a breakout board. It’s compatible with any 3V or 5V microcontroller or computer, and we’ve included SparkFun Qwiic compatible STEMMA QT connectors for an easy, solder-free connection.

Our comprehensive support includes example codes for Arduino or compatible boards, needing at least 20KB RAM, or Raspberry Pi with Python, where you can also leverage the SciPy library for advanced processing. We've simplified the setup, so you can start experimenting with just a few lines of code.
