Pir Sensor How It Works As Follow：
PIR , pyroelectric infrared sensor, is normally known as a motion detector. It is a passive sensor based on measuring infrared light radiating from objects within its field of view. The detector itself cannot emit infrared. It is commonly used in burglar alarms and smart lighting applications.
Owning very strong R&D Center, Senba can research and develop the pyroelectric infrared sensor independently. Among those china sensor manufacturer, Senba Sensor has become the first owner of this special technology enterprise in China. We are awarded as "Henan high-tech enterprises" in 2006 and awarded as "Notional high-tech enterprises" in 2012.
