SparkFun IR Array Breakout - IR Thermal Camera Module MLX90640 - FOV 55 - Qwiic - SparkFun SEN-14844

Index: SPF-21292
SparkFun module equipped with an IR matrix - a thermal imaging camera based on the MLX90640 chip . The measuring matrix detects objects on the basis of the heat emitted by them, its resolution is 32 x 24 px. The temperature measurement angle by the camera is 55 ° x 35 °. The device allows you to measure the temperature in the range from -40 ° C to 300 ° C with an accuracy of +/- 1.5 ° C. It uses the popular I2C interface for communication. On the board you can find two Qwiic connectors that facilitate connection with the main module equipped with the same type of connector.

SparkFun IR Array Breakout has a high demand of RAM and Flash memory to perform the necessary calculations. Main modules based on microcontrollers with less memory, eg Arduino UNO, may be insufficient to support the MLX90640 sensor. The manufacturer recommends using systems with more memory. When using Arduino , a minimum of 20 KB of RAM is required - SAMD21 (M0) or SAMD51 (M4).
