Motion detectors are useful smart home devices for creating simple automations, such as turning on your lights when you enter ...

While there are loads of impressive and complex projects here on Hackaday, sometimes it’s the simple ones that really speak to us. In this case we were presented with [Isabell Park]’s easy-to-follow ...

The main principle of the circuit is to provide security using PIR sensor. This can be used in the museums to protect the valuable things and also in defense applications to detect the humans in war ...

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) ...

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.

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 ...

The FP1E’s millimeter wave technology provides for a much more nuanced look at whether a room is occupied or not, but you’ll need one of Aqara’s Zigbee or Matter smart home hubs to use it. Whatever ...

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...

OPTEX, the global leader in outdoor detection innovation, is pleased to announce the QX Infinity Series (QXI), a family of high or low mount outdoor PIR and dual-technology sensors that provide a 120° ...

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 ...
