Digital Control Circuit Sensitive Element BS312
Overview
PIR sensor sense the motion object, always used to detet the human. There is a detect rang for the PIR sensor. When a people move in or out of the detect rang, the PIR sensor will be triggered. PIR sensor are low-power, small, easy to used. For this reason it can be used for the alarm system and lighting control. PIR sensor also named passive infrared, Pyroelectric or IR motion sensor.
Features of BS312 Low Voltage PIR Sensor
Power adjustable, save more energy
Two-way differential high impedance sensor input

Applications of BS312 Wide Angle PIR Sensor
Intelligent security- burglar alarm
Wireless infrared detection alarm, uses advanced signal analysis and processing technology. When the intruder enters through the detection area, it sends alarm signal to control panel.
The PIR sensor is suitable for home, residential area, factory, shopping mall, warehouse, and offices.
FAQ of Digital PIR Sensor
PIR sensors are excellent in human and animal detection. They are mostly used in triggering an intruder alarm and activate household appliances upon the presence of a human.
No, alarm motion sensors do not work through glass. Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated.
