Passive infrared sensor - Wikipedia

The PIR sensor is typically mounted on a printed circuit board containing the necessary electronics required to interpret the signals from the sensor itself. The complete assembly is usually contained within a housing, mounted in a location where the sensor can cover the area to be monitored. PIR motion sensor design . The housing will usually have a plastic "window" through which the infrared ...

Best Practices: Occupancy Sensor Placement and Technology

PIR Sensor False Triggers PIR sensors utilize infrared radiation impinging on the sensor to detect motion. A change in temperature in the space can result in an erroneous reading from the sensor. HVAC vents that cause moving air across the sensor, or situations that cause the sensor housing to heat up and cool down, will cause false triggers. Sensitivity settings can be manipulated to help ...

Using PIR Sensors for Motion Detection – Upverter Blog

2019-10-17· Each PIR sensor unit consists of two individual infrared-sensitive halves. As the radiating body (a person in our case) moves in front of the sensor, one sensor will be crossed before the other. For this short duration, the first sensor will capture a larger amount of radiation than its counterpart, creating a positive differential voltage. Similarly, while leaving a PIR motion sensor’s ...
