How accurate is PIR sensor. I made a project motion sensor light for washroomMotion sensor light for washroom . It is working fine. But sometimes it's get activated without any motion. It is actually installed in my washroom and the light sw on sometimes even when no one is present in the washroom.
Either the device is so sensitive that it even senses housefly or it's a simple bug in the sensor.
Thank you for using our forum, but please be informed that NXP does not offer any passive infrared sensors or PIR-based motion detectors, so you may not get here the answer you are hoping for.
