How to use Pyroelectric ("Passive") Infrared Sensors (PIR)

The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can ''see'' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When ...

PIR sensor problem | Talk Electrician Forum

28/08/2015· The sensor in a PIR or motion detector is actually split in two. The reason for that is it is looking to detect motion change and not average IR levels. The two halves are wired up so that they cancel each other out. If one half sees more or less IR radiation than the other, the output will swing high or low depending on the type of PIR. If your sensor is normally closed switch then when the ...

PIR sensor range Light when and where you need it with ...

A PIR sensor operates using positive differential change. Two IRsensitive slots sit in front of the lens, with their field of “vision” determining the range of detection. While ‘idle’, the ambient level of infrared detected in the room (naturally emitted by all objects) is the same on both slots. The minute an object, person or animal moves through the detecting zone, it is sensed by ...

PIR Sensor (55528027)

The PIR Sensor requires a ‘warmup’ time in order to function properly. This is due to the settling time involved in ‘learning’ its environment. This could be anywhere from 1060 seconds. During this time there should be as little motion as possible in the sensors field of view. Sensitivity The PIR Sensor has a range of approximately 20 feet. This can vary with environmental conditions ...
