*Power supply:3×1.5V AAA battery                                                  

*Sensor can be placed at the entrances of garage,store,and house                   

*Traffic and movement can be detected within infrared induction distance                                                                                                     

*Easy installation within some minutes                                                  

*1 sensor can work with unlimited receivers                                  

*How does it work:A passive infrared (PIR) sensor detects the moving heat created by an automobile's engine(or any other noticeably hot object moving at sufficient speed).The sensor should be deployed outdoors,where it will have a clear view

*Placement Guide:To know exactly where you should place the sensor,and which way you should aim the PIR,it's worth thinking about how the PIR sensor works,the range and area it can cover,as well as what may "fool" it into generating a false reading.The PIR is,as its name suggests,a passive sensor(unlike a security camera with IR LEDs for night vision,which is active infrared).Basically,all objects emit some infrared radiation(we commonly call it "Heat") and the sensor looks for any of this radiation which moves.The upshot of the passive sensor is the low battery consumption-batteries last up to months at a time,much longer than active infrared systems
