A PIR (Passive InfraRed sensor) is a sensor detecting movement throught infrared (heat) from human (mammals and birds).

Example of devices with Z-Wave technology:

You have pets, and your PIR detects them. How to do?

  • You can mask the bottom part of the PIR (with paper). Have a try adjusting the mask until you have no detection. Most "pet compatible" sensor works masking the bottom part.
  • It may be easier to settle the sensor at a lower position (1 m insted of 2m), and to view horizontaly (and not downward).
  • You can also decrease the sensibility (parameter #1 in increase in FGMS-001). You decrease the sensibility until you have no detection (but sensibility will also decrease for humans).

To try many times: Use a silent alarm (with mail or push notification) to check if the settings are OK.

There are professionals sensors, especially for outdoor use. They use the breaking of 2 beams PIR to accommodate animals (and the microwave in addition to limit false alarms on shrubs and reflections). These sensors can be connected to a Z-Wave opening sensor for wireless communication. Example: Optex VXI-RDAM
