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

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.

We all know that feeling: you've turned the lights off and are almost asleep when you hear that infamous buzz. A mosquito is hunting in your bedroom. The dance commences. You could turn on the lights, ...
