BS612 is a pyroelectric infrared sensor
that integrates digital intelligent control circuit and human body
detection sensitive element in electromagnetic shielding cover. The
human body detection sensor couples the sensed human body 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 will be a
timed REL level output. The OEN enable terminal enables the REL output
or automatic control by the light sensor. Sensitivity and time
parameters are set by voltage divider resistors. All signal processing
is done on-chip.
Digital signal processing, no drift and aging
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
