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.

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 ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Several companies are trialing sample versions of a passive ultrahigh-frequency (UHF) RFID sensor tag designed to enable users to capture data such as temperatures, strain or weight, using a standard, ...

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.

Staff Sgt. Jacob Rascon, right, and Sgt. David Hendrixson, both assigned to 3rd Brigade Combat Team, 101st Airborne Division (Air Assault), analyze prototyped cyber field equipment during Cyber Quest ...

Motion detection has become an essential ingredient in traditional electronic security and now it is being utilized in access control and video surveillance systems. With more applications and so many ...

Smart lights are a great way to enhance home security. Being able to flip on the lights remotely or automatically, you can give the impression that someone is home and expose potential intruders. It’s ...

Want to know the temperature of machine parts before they overheat and cause damage? Monitor water-intolerant assets without opening the container to check each one? Detect strain in concrete? Save ...

A few weeks ago, Aqara was in the news with the release of its new P2 motion sensor. I am a big fan of motion sensors for smart homes as they allow for some pretty rad automations based on who’s in a ...
