Review on πŸ€– DAOKI 5Pcs PIR IR Module HC-SR501: Efficient Infrared PIR Motion Detector for Raspberry Pi Kits with Dupont Cable by Ryan Lawson

Revainrating 2 out of 5

All you need is a current specification from the manufacturer.

This compact peer module is ideal for a physical detection, alarm and interaction system I am building for a server room. I'm currently using it on 5V. It would be nice to have a datasheet so I can determine the effect of changing the voltage and current applied to the module. I've posted an image of an Arduino sketch that I use to determine how long the output pin stays high after motion is detected. If you see a picture you can use the code. Change the PIN to the one you use.

Pros
  • Few competitors
Cons
  • Unreliable
