Grove - Thermal Imaging Camera / IR Array MLX90640 - 55°

This compact Grove thermal imaging module uses a 32×24 MLX90640 sensor array to detect and visualise temperature changes in its surroundings. With a measurement range from -40°C to 300°C and an accuracy of ±1.5°C, it's ideal for detecting heat patterns from a distance and displaying low-resolution thermal images. Data is transferred over I2C, making integration straightforward. However, due to the memory demands of thermal image processing, a more capable microcontroller is required with at least 20k RAM - boards like the Arduino Uno are not suitable. The sensor has a field of view of 55°×35° and supports refresh rates from 0.5Hz to 64Hz. It uses the Grove I2C interface for plug-and-play connection and requires a Grove cable. Libraries for Arduino and Python are available to get started quickly. Features
