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
You can buy the sensor as a standalone chip, but most users prefer a which includes necessary voltage regulation and I2C pull-up resistors.
Capable of up to 64 FPS , though practical limits for many microcontrollers are around 16 Hz due to I2C communication speeds. mlx90640 buy
Typically detects temperatures from -40°C to 300°C with roughly 1°C accuracy .
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: The is a popular, cost-effective far-infrared (FIR) thermal
Uses I2C , making it compatible with Raspberry Pi, Arduino, and ESP32. 2. Choosing Your Field of View (FOV)
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. Key Specifications to Know Before Buying You can
Ideal for room monitoring, human presence detection, or mounting close to a target. 3. Recommended MLX90640 Modules and Retailers
