Review on π¦ 5pcs HC-SR501 Human Body Pyroelectric Infrared PIR Motion Detector Sensor Module by Oiyagai by Gordon Turman
They're not precise enough
Even after many adjustments, three out of five people can't see a person walking directly in front of them half the time. I haven't tested the other two and intend to desolder the PIR sensor and build my own circuit instead.
- Sleek design
- No automatic steering
