NS612

NS612 Product Introduction

NS612 is a type of PIR sensor that integrates a digital control circuit and a human detection sensor within an electromagnetic shielding housing. The human body detection sensor couples the sensed human movement signal to a digital intelligent integrated circuit chip via a very high-impedance differential input circuit, and the digital intelligent integrated circuit converts the signal into an ADC digital signal. When the PIR signal exceeds the selected digital threshold, a timed REL level output is triggered. The OEN enable terminal allows for REL output or automatic control via a light sensor. Sensitivity and time parameters are configured through a voltage-dividing resistor. All signal processing is performed on a single chip.

NS612 Product Features

• Digital signal processing

• High power supply rejection ratio, anti-radio frequency interference(mobile phone,WiFi,etc.)

• A second-order Butterworth bandpass filter with built-in infrared sensor to shield input interference at other frequencies

• Sensitivity,Ontime, and light sensor Schmitt REL output.

• Ontime adjustable

• Good stability and effective suppression of repeated malfunctions

• Low power consumption and simple application circuit
