5PCS IR Pyroelectric Infrared IR PIR Motion Sensor Detector Module HC-SR501
Nov 19, 2016
Works as advertised
Easy to set up and adjust, Has option to add an L.D.R. ( Photocell ) so it won't activate in daylight. I use these to turn on a string of LEDs when I enter a room. Bottom line: They work.
HC-SR501 Infrared PIR Motion Sensor Module for Arduino Raspberry pi new

They work
I have never had a problem with these babies. They just work. And you can install an LDR if you want so they are not activated during the day. ( If you are using them to turn a light on that is ) If you are using it to activate an alarm of some type then don't do that, It would be dumb. Easy to use, Inexpensive, and the girls love them.
