CircuitDigest
With an aim to make Thermal Camera affortable for hobbyists and makers we built this DIY thermal camera using an ESP32 microcontroller and an MLX90640 thermal sensor. The camera captures thermal images with a resolution of 32x24 pixels and features a 2.4-inch display for visualization. It offers adjustable refresh rates, various color palettes, and temperature measurement capabilities between -40°C and 300°C.
