Typically detects temperatures from -40°C to 300°C with roughly 1°C accuracy .
The is a popular, cost-effective far-infrared (FIR) thermal sensor array with a resolution of 32x24 pixels (768 total sensors). It is widely used by hobbyists and engineers for non-contact temperature measurement, human detection, and thermal imaging. 1. Key Specifications to Know Before Buying mlx90640 buy
32x24 pixels. This is a significant step up from the 8x8 resolution of alternatives like the AMG8833, allowing for actual heat-vision visualization rather than just simple presence detection. Typically detects temperatures from -40°C to 300°C with
Uses I2C , making it compatible with Raspberry Pi, Arduino, and ESP32. 2. Choosing Your Field of View (FOV) Uses I2C , making it compatible with Raspberry
Capable of up to 64 FPS , though practical limits for many microcontrollers are around 16 Hz due to I2C communication speeds.
Best for longer-range detection or identifying specific objects.
