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.

Presence detection finally works in my house, and there isn't a motion sensor involved.

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.

A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) ...

Detecting and measuring movement is an essential element for many industrial and commercial IoT applications – from lighting and security to assisted driving. Motion detection systems consist of a ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

GlacialLight has added the GL-PIR10C, a versatile infrared motion sensing switch, to its popular range of lighting products.This passive infrared (PIR) motion sensor can be connected to a wide range ...

Panasonic has expanded its PIR (passive infra-red) motion sensor portfolio with the introduction of PaPIRs+ for building automation and smart infrastructure. PaPIRs+ delivers enhanced detection ...

Smart sensor placement matters. Learn exactly where to install motion sensors in your home for complete security coverage without missing a beat.

Sometimes the smallest and most utilitarian thing can make the biggest difference in your home. With a proper night light, for example, there are a lot fewer accidents caused by trying to navigate in ...
