The MLX90640 IR Array Breakout features a thirty two by twenty four array of thermopile sensors that functions as a low resolution thermal imaging camera. It allows detection of surface temperatures from several feet away with an accuracy of plus or minus one point five degrees Celsius in best conditions. Communication is handled entirely through I2C which makes integration simple and reliable. The board supports the Qwiic connection system for quick plug and play wiring and also includes standard zero point one inch spaced pins for breadboard use. This version of the breakout provides a fifty five by thirty five degree field of view and supports a wide temperature measurement range suitable for many thermal sensing applications.
Notes:
The MLX90640 sensor requires significant memory and processing power to convert raw pixel data into temperature values. Standard Arduino Uno boards do not have sufficient RAM or flash memory for these calculations. A microcontroller with at least twenty thousand bytes of RAM is required such as Teensy three point one or higher ESP8266 or ESP32.
