How PIRs Work | PIR Motion Sensor | Adafruit Learning System

Jan 28, 2014· PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.


Motion Detectors for Security Systems: Which Is Best for You?

Sep 19, 2018· And since there are multiple motiondetecting sections in each sensor, each plastic cover is actually split up into several – or numerous – sections, each its own Fresnel lens. When this is done properly, most PIR motion detectors will have an effective range between 30 and 50 feet in about a 180degree field of view.


How do I reduce the sensitivity of my PIR Sensor?

Feb 27, 2020· PIR sensor detects a human being moving around within approximately 10m from the sensor. This is an average value, as the actual detection range is between 5m and 12m. PIR are fundamentally made of a pyro electric sensor , which can detect levels of infrared radiation.
