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.

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.

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.

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 ...

Combination flame & passive infrared motion sensor with two output modes including “And” detection and “Individual” modes. Designed to minimize nuisance alarms where fast acting spark/flame may be ...

Designed to expand lighting options for enclosures, the SL 025 Slimline provides both illumination and a motion sensor, making it particularly useful in enclosures with glass doors. The passive ...

The RemoBell W’s passive infrared sensor and its remote wireless chime are high notes, but we remain less than enthused with the Remo+ app. Remo+ jumped into the video doorbell product with both feet, ...

I love Aqara’s products, and if you love HomeKit, it’s a vendor you’ll want to follow. They make incredibly easy-to-use and reliable smart home products at prices that won’t empty your bank account.

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 ...

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 ...

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 ...
