Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada. The ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

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.

Geneva, Switzerland, July 24, 2023 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, is launching a novel ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

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 ...
