The Adafruit MLX90640 IR Thermal Camera Breakout features a 24×32 array of infrared thermal sensors that returns 768 individual temperature readings over I2C. It's an affordable way to add heat-vision to any microcontroller or Raspberry Pi project — like a miniature thermal camera you can integrate into your own designs.

The sensor measures temperatures from −40°C to 300°C with ±2°C accuracy (in the 0–100°C range) and captures frames at up to 16 Hz. This is the 110° field-of-view version, ideal for wide-area monitoring. The breakout includes a 3.3 V regulator and level shifting, so it works with both 3.3 V and 5 V systems, and features STEMMA QT / Qwiic connectors for solderless I2C wiring.
