Grid-EYE click

Description of product

Description

Grid-EYE click is a 8x8 thermal array sensor-detector that carries the AMG8853 infrared array sensor from Panasonic. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over I2C interface.

Use the Grid-EYE click to detect absolute surface temperature without any contact. Or use it to detect the movement of people and objects.

Take a look at how Panasonic's AMG8853 64 thermal sensors see a moving hand:

AMG8853 sensor features

The AMG8853 is made out of 64 individual thermal sensors. It can build an image according to the heat it detects. You don’t need light to form a picture.

The temperature measuring range is from -20°C to +100°C

The detecting distance is 5m, the viewing angle 60 degrees.

The AMG8853 has a built-in thermistor for suppressing ambient temperature noise. 

The I2C levels and address are jumper selectable, while the AMG8853 is supplied with designated voltage.

Infrared sensor

Infrared waves are outside the visible spectrum of the human eye, just like radio waves. Even though people can’t see infrared waves, they can certainly feel them, in the form of heat.

Our bodies emit heat or infrared radiation, and the AMG8853 thermal array sensor can detect it.
