Review on π€ DAOKI 5Pcs PIR IR Module HC-SR501: Efficient Infrared PIR Motion Detector for Raspberry Pi Kits with Dupont Cable by Sam Anez
Very sensitive and not well shielded from EMI.
This PIR is extremely sensitive and susceptible to interference from the RPi 3B+ it is connected to. Had to move the PIR about 2ft away from the RPi or you would get a lot of false positives. The device is protected against RF and electromagnetic interference, and false alarms have disappeared.
- Best in its niche
- I will add later
