Pololu - PIR Motion Sensor

The passive infrared (PIR) motion sensor detects movement of infrared light sources with wavelengths ranging from 7 μm to 14 μm. Since people emit infrared radiation from 8 μm to 14 μm, this an excellent sensor for detecting human movement. Two infrared detector “pixels” allow the detector to filter out changes affecting the whole sensing area, like weather or light.

What is PIR & Benefits of PIR Cameras | Swann Security

May 28, 2017· The camera has a PIR sensor, the same technology used in alarm systems, to detect moving heat-generating objects, such as people, large animals & cars, to trigger recording and alerts. True Detect eliminates false triggers from traditional motion detection, such as falling leaves, small birds & plants moving with the wind.

Radar sensors | Baumer USA

The radar sensor is also available in a configuration, where it operates similar to a light barrier. Via a special teach-in-algorithm the sensor learns the reflector position. After teaching the sensor monitors the reflector position. If an object breaks the line of sight between the sensor and reflector, the sensor …

PIR Motion Sensor |

PIR Motion Sensor. A PIR Sensor can tell when something nearby moves. The sensor detects the pattern of infrared energy in its surroundings. If the pattern changes, the sensor outputs a high signal. The Propeller microcontroller only needs to monitor this signal with an I/O pin to know if something is moving around nearby.
