Understanding Active & Passive Infrared Sensors (PIR) and ...

11/09/2018· Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. That may mean it triggers an alarm, notifies ...

Passive Infrared Sensors /PIR Sensors Applications

The PIR sensor detects unusual activities in an environment and sends a signal to the alarm panel for processing. Alarm type PIR sensors consist of four common types, including magnetic contact switches, glass break protection devices, microwave beam, photoelectric devices, and the more popular motion detection devices. Regardless of the type, PIR-based security alarm systems are a more ...

PIR Sensor Interfacing with PIC16F877A ⋆ EmbeTronicX

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 ...
