A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

Detecting and measuring movement is an essential element for many industrial and commercial IoT applications – from lighting and security to assisted driving. Motion detection systems consist of a ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

In the last several years, thermal imaging cameras have become mainstream, finding their way into several front-line manufacturers’ IP camera offerings. At the Association for Unmanned Vehicle Systems ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

Sensors vary widely and can monitor and detect a variety of sources, such as light, heat, motion, moisture, and pressure. Typical sensors used in smart cities can sense temperature, proximity, ...
