Review on πŸ”¦ 5pcs HC-SR501 Human Body Pyroelectric Infrared PIR Motion Detector Sensor Module by Oiyagai by Peter Parks

Revainrating 2 out of 5

They are not precise enough

Even after many adjustments, three out of five may not notice that half the time a person is walking directly in front of them. I haven't tested the other two and intend to desolder the PIR sensor and build my own circuit instead.

Pros
  • GOLS certified
Cons
  • Only available in black
