What type of motion sensor is used to detect heat?
The first most common type is the Passive Infrared (PIR) motion sensor. This type of motion sensor gets set off by detecting heat (infrared energy) given off by humans, animals, and anything else with a heat signature. It is important to note that only changes in temperature will set off a PIR motion sensor, not constant temperature.
How many slots are there in a PIR detector?
A PIR motion detector contains two slots which are made of material capable of detecting Infrared energy.
Why does my motion sensor turn off?
With an infrared sensor, if light is shining through trees onto the motion sensor, wind can set off the motion sensor when it blows the leaves causing a change in light levels. With an microwave type motion sensor, if an object is blown past the motion sensor due to high winds, this can cause the motion sensor to be set off.
What happens when a body moves in front of a PIR sensor?
When a body like a human or animal moves in front of the PIR detector, it will cross one half of the PIR sensor which causes a positive differential change between the two slots. This is what sets off the PIR motion sensor. A note should be made that a change in ambient temperature will not set off the motion detector as both slots will see ...
How does a motion detector work?
This type of motion detector uses electro-magnetic radiation to detect motion. An electro-magnetic wave is sent (through a transmitter), which then bounces off objects and is reflected back to the receiver. The receiver can use this information to see whether an object is moving within a given space or not.
