The motion sensor was designed using a pyroelectric sensor which is essentially a FET with a window in the case opening onto an infrared-sensitive gate. The circuit is monitoring the changes in the ...
IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...
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 ...
