PIR and US Occupancy Sensor Technologies - Leviton

General Rules: Optimal placement for a PIR sensor is essential. PIR sensors have a specialized lens used to create “detection zones.” As the mounting height and distance from the sensor increase so does the zone coverage, requiring larger movements for detection. This is referred to as Major Motion. Minor Motion on the other hand, means that less movement is required for detection. I

Pyroelectric Infrared Sensor PIR - Philadelphia University

PIR Sensors •The PIR sensor can sense the change in the amount of infrared energy within small distances, approximately up to 10 inches. For detecting movements at longer distance (up to 10 m), infrared radiation has to be focused. This focusing is done by a Fresnel lens. A Fresnel lens divides the whole area into different zones. Any movement between zones leads to a change in the IR ...
