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 ...

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.

Truck-Lite recently rolled out a new feature for its Super 80 LED [light emitting diode] interior trailer lamp – an infrared [IR] motion sensor to automatically turn the trailer dome light on and off, ...

Meross has announced the launch of its new 3-in-1 smart sensor, the MS605. It uses triple detection technology, combining radar, infrared and light sensing, to reduce false alerts and deliver more ...

A smart home is more than a smart house.

For many years, one of the most common solutions for saving energy has been to “turn out the lights and dial down the thermostat.” It’s a given that unoccupied space is one of the biggest energy ...
