Sparkfun IR Array Sensor - 110 Degree FOV (MLX90640)

The MLX90640 is a compact and highly efficient 32x24 pixel thermal infrared array sensor, housed in a standard 4-lead TO39 package with a digital interface. It features a wide 110°x75° field of view and can measure temperatures ranging from -40°C to 300°C. With 768 FIR pixels, it integrates an ambient sensor to monitor the chip's temperature and a supply sensor to measure VDD, storing all outputs in internal RAM accessible via I2C.

This sensor is ideal for a variety of applications, such as thermal imaging, motion detection, and temperature monitoring in industrial settings. Its broad field of view makes it suitable for capturing detailed thermal maps in large areas, while its wide temperature range allows for use in extreme conditions.

One of the key benefits of the MLX90640 is its ability to provide precise and reliable thermal readings, making it a valuable tool for engineers and developers in need of accurate temperature data. The integration of ambient and supply sensors ensures consistent performance and reliability.

It's important to note that due to the complex calculations required to process raw pixel data into temperature information, a powerful microcontroller with at least 20,000 bytes of RAM is necessary. A Teensy 3.1 or higher is recommended to handle these computations effectively, ensuring smooth and accurate data processing.
