PIR HC-Sr505 usage - Sensors - Arduino Forum

May 21, 2021· I have been wanting to try the common mini PIR HC-Sr505 from Ebay. But, I found the Delay was too long, about 10 seconds between Sense On and Off. I replaced the TC cap of (?) with 22pF - 100pF to speed up the Sense Toggles to - 1sec. This seems to perform its function. The only problem I see , is the Boot-up takes about 10 seconds - before the Sensor Out turns Off. …

arduino uno - HC-SR505 PIR Sensor only outputting HIGH ...

Jan 30, 2016· HC-SR505 PIR Sensor only outputting HIGH. I recently bought an HC-SR505 Mini PIR sensor. I connected its positive to my Arduino UNO's 5v, output to digital pin 2, and ground to ground. I used Adafruit's code to test it, but all the serial monitor displayed was "Motion detected", which meant the PIR was always on a HIGH state. I then also tried ...
