Mounting the PIR Sensor:
The key to successful operation of any PIR sensor is choosing the correct location. A sensor mounted in a unsuitable location has the potential to cause false triggers and reduce performance. The main rules that should be followed are:
1) Mount the PIR into a corner of a room.
2) Avoid heat spots from bright lamps suddenly turning on or off.
3) Do not install immediately above a radiator.
4) Do not install in a glass roof conservatory.
How PIR's Work (passive infrared detector):
All PIR sensors detect changes in infra-red radiation, in the form of heat emitted by a number of bodies including people, cars and to a lesser extent, dogs or other small animals. The bigger the body, the more infra-red radiation isemitted and the easier it is for a PIR sensor to detect.
The field of view is the area in which changes in infra-red radiation can be detected. The field of view can alter with changes in temperature and the size of the heat source.
The construction of the PIR and Fresnel Lens divide the field of view into a number of zones both vertically and horizontally.
