Review on DAOKI 5PCS Human Motion Sensor HC-SR505 Mini Infrared PIR Detector Module For Arduino Body Sensor Switch With Dupont Cable Female To Female by James Vilchez
Very sensitive and not well shielded from EMI.
This IR sensor is very sensitive and susceptible to interference from the RPi 3B+ to which it is connected. Had to move the PIR about 2ft away from the RPi or you would get a lot of false alarms. The device is protected against RF and electromagnetic interference, and false alarms have disappeared.
- Comfortable
- Available in white only
