Introduction

The product is a type of intelligent PiR sensor which integrates digital control circuit and body sensitive element in one electromagnetic shielding. The signal inputs from sensitive element to digital circuit via a high impedance differential. The digital circuit converts the input signal to 15bit ADC digital value. When the PIR signal above the selected threshold, there will be a REL output. The parameter of time are set by resistance to control the time delay of application continuous work. All signals are processed digitally.
