Analog PIR SENSOR D218D

Overview

The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature. Two channel sensing elements are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved. Our products can be used in many applications. Such as smart toys, automatic light switch, induction door, etc., especially for smart toys application.
