pir sensor circuit
My PIR sensor circuit is sensitive to RF field variation.
Please check attachement for the circuit.
At the moment when RF field got applied or removed or variated. TP13 output a trigger signal which is strong enough to trigger a detector.
Seems its the voltage variation when subject to RFI leads to the false trigger. How to get rid of this ??
Thanks a lottttttt.
