NS612 is a type of PIR sensor which
integrates a digital control circuit and a human detection sensor in an
electromagenetic shielding housing.The human body detection sensor
couples the sensed human movement signal to the digital intelligent
integrated circuit chip through 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, there is a timed REL level output. OEN
enable terminal enables REL output or automatic control through light
sensor. Sensitivity and time parameters are set through a partial
voltage resistor. All the signal processing is done on the chip.
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
