Reusing Passive Infra-Red Sensors

\\ ===== Overview ===== Passive infra-red sensors are used in many applications to detect the presence of people, eg security lights. I expect that when those devices become faulty it is not the PIR device that has failed but some other component (most likely in the power supply). ===== Hardware description ===== ===== PIR modules ===== On the [[:electronic:pir:sidebar|sidebar]] there is a list of PIR modules, the linked pages include pinouts and whether there is an Arduino driver for them. ====== References and Additional Resources ====== * [[https://www.instructables.com/id/PIR-Motion-Sensor-Tutorial/|PIR motion sensor tutorial]] * [[https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/how-pirs-work|Another PIR motion sensor tutorial]] * [[http://www.glolab.com/pirparts/infrared.html|How Infrared motion detector components work]]
