This infrared alarm barrier can be used to detect persons passing through doorways, corridors and small gates. The transmitter emits a beam of infrared light which is invisible to the human eye. The ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

An IR repeater system takes Infrared (IR) light coming from your remote controller and converts it to an electrical signal that can be easily distributed over electrical wiring to one or more IR ...

Tempe, Arizona - Southwest Microwave, a leading global supplier of perimeter intrusion detection systems, has announced the introduction of the advanced Model 420 Passive Infrared (PIR) Sensor for ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

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 ...
