Digital infrared motion sensor 
 

Digital infrared motion sensoris the PIR sensor that combines the digital intelligent control circuit with 
the  human  detect  element  in  a  cover with EMI  feature. The  element  detects  human 
motion signal, and couples  it  to  the digital  intelligent  IC via a high  impedance  input 
circuit, then the IC transforms the motion signal to 15digits ADC signal, when the PIR 
signal exceeds the number set, REL signal  is output. All the signal process  is done  in 
the IC. 

■   Features and Benefits 
  
* Digital Signal Processing (DSP) 
* Power adjustable, save more energy 
* Two-way differential high impedance sensor input and temperature compensation 
* Built-in filter, screen the interference by other frequency 
* Excellent power supply rejection, Insensitive to RF interference 
* Schmidt REL output 
* Low voltage, low power consumption, instantaneous settling after power up
