AMG8833 8×8


The AMG8833 infrared camera sensor is an 8×8 infrared thermal sensor array. When connected to your microcontroller (or Raspberry Pi), it will return a set of 64 individual infrared temperature readings via I2C. It’s like those fancy thermal cameras, but it’s compact and simple and easy to integrate. The AMG8833 offers higher performance than the previous AMG8831. The sensor only supports I2C and has a configurable interrupt pin that can be triggered when any single pixel is above or below your set threshold.

It can detect humans from a distance of up to 7 meters (23) feet. It is a perfect fit for creating your own human detector or mini camera. We use this breakthrough code on Arduino or compatible (sensor communicates via I2C) or on Python’s Raspberry Pi. On the Pi, thanks to the image processing help of the SciPy python library, we can insert an 8×8 grid and get some very good results!

MLX90640 32×24



Provide PC software to directly display temperature imaging graphics.

The module contains a single-chip microcomputer, the serial port directly outputs 768 temperature data, and the USB turns ttl directly to the computer to see the data.

The original I2C interface of mlx90640 is retained, and the sensor chip can be directly operated by an external MCU (PS is connected to GND).

Field of view angle: 110*75° (large angle, suitable for close-range measurement)
