The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

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

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

GlacialLight has added the GL-PIR10C, a versatile infrared motion sensing switch, to its popular range of lighting products. GlacialLight has added the GL-PIR10C, a versatile infrared motion sensing ...

Motion detectors are widely known for their role in home security systems, but their usefulness extends far beyond guarding ...

Panasonic Industry has introduced a new passive infrared (PIR) motion sensor featuring a flat lens design, marking the first product to incorporate the company’s PaPIRs+ sensing technology.

A smart home is more than a smart house.

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body. All objects, living or not, ...

The motion sensor switch circuit can automatically turn on a water sprinkler but you can easily use it as a motion sensor light switch or motion activated alarm too. Before beginning the construction ...
