Human body infrared sensor module
Human body infrared sensor module
The module detects human activity through the principle of pyroelectricity. Once a person enters the detection area, the sensor will send a high-level signal. The Fresnel lens filter attached to the surface can improve the recognition sensitivity and reduce the effect of environmental interference. This module is often used in corridor switches, visitor notification devices, etc.
