DC 12V 24V PIR Motion Sensor
Fortunately, pin 9 of BISS0001 is reserved for this case.
It is designed so that when the input voltage Vc on pin 9 is high, the PIR input is enabled and when Vc is low, the PIR input is disabled (Vc <0.2 Vdd = disabled).
This can be achieved by using an LDR (photoresist) “Trigger Disable Input” between pin 9 and ground.
