Sparkfun IR Array Sensor - 55 Degree FOV (MLX90640)

The MLX90640 is a compact, fully calibrated thermal infrared array featuring a 32x24 pixel resolution. Encased in a standard 4-lead TO39 package, it offers a digital interface for easy integration. Equipped with an ambient sensor and a supply sensor, it accurately measures the ambient temperature and VDD. The sensor's outputs are stored in internal RAM, accessible via I2C. With a 55°x35° field of view, it can measure temperatures ranging from -40°C to 300°C.

The MLX90640 is ideal for applications requiring precise thermal imaging, such as home automation, industrial monitoring, and safety systems. Its ability to detect temperature variations across a wide area makes it perfect for creating thermal maps or detecting heat leaks in buildings. In industrial settings, it can be used to monitor machinery temperature, ensuring optimal performance and preventing overheating.

One of the standout features of this sensor is its high sensitivity to temperature changes, providing accurate readings even in challenging environments. Its compact size and digital interface make it easy to integrate into various projects, offering flexibility for developers and engineers.

To harness the full potential of this sensor, a microcontroller with at least 20,000 bytes of RAM is necessary due to the complex calculations required to process raw pixel data into temperature readings. The Teensy 3.1 or higher is recommended for this purpose, ensuring seamless operation and reliable performance.
