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