Mlx90640 Buy Link

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.

Uses I2C , making it compatible with Raspberry Pi, Arduino, and ESP32. 2. Choosing Your Field of View (FOV) mlx90640 buy

When buying an MLX90640 module, you must choose between two primary lens types. Your choice depends entirely on your project's distance and area requirements: 32x24 pixels

Capable of up to 64 FPS , though practical limits for many microcontrollers are around 16 Hz due to I2C communication speeds. Typically detects temperatures from -40°C to 300°C with

Typically detects temperatures from -40°C to 300°C with roughly 1°C accuracy .

You can buy the sensor as a standalone chip, but most users prefer a which includes necessary voltage regulation and I2C pull-up resistors.

Best for longer-range detection or identifying specific objects.
