Home Alarm System. As its ability to sense warm, moving objects such as people walking into a room is coupled with simplicity and cost effectiveness.
1. Can PIR sensor detect animals?
PIR sensors are excellent in human and animal detection. They are mostly used in triggering an intruder alarm and activate household appliances upon the presence of a human.
2. Do PIR sensors work through glass?
No, alarm motion sensors do not work through glass. Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated.
