Overview of pir sensor alarm system
Senba PIR Motion Sensors are passive infrared type sensors. Working
temperature is -20~ 85℃. There are 3type for PIR sensor, 3pins, 4pins, 6pins. For 3 pins type, 2s not adjustable. For 4pins, delay time adjustable. For 6pins, delay time, sensitivity, lighting adjustable.
Robust Design Against False Starts
Low Curvature Lens
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.
1.Why is PIR sensor called passive?
The sensor is called passive because it doesn't emit light to get measurements. The sensor in PIR is actually split into two parts. The reason for that is to measure motion. ... The sensor is also sensitive enough to even detect IR radiation source movement while the object is already in it's field of view.
2.How far can a motion sensor detect?
Most low-cost motion detectors can detect up to distances of at least 15 feet (4.6 m).
