Motion detection is the magic ingredient in the current wave of do-it-yourself home security cameras. Thanks to built-in sensors that vigilantly monitor their field of view for movement, you can go ...

I set up my $25 WyzeCam v2 with the PIR Motion Sensor and Sensor Bridge accessory to catch some hummingbirds feeding. I can't use video motion detection because the feeder is constantly swaying in the ...

Using the latest Raspberry Pi 4 Model B mini PC, you can easily create a sophisticated security camera system complete with a motion sensor. This setup will automatically send images taken using a ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

California-based KODA’s latest security camera introduces its first motion-activated floodlight + alarm offering with the new KODA LightCam. The camera includes some impressive features including the ...

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.

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...

Thieves beware. If you prowl around [Matthew Gaber]’s place, you get soaked by his motion activated super-squirter. Even if he’s not at home, he can aim and fire it remotely using an iPhone app. And ...
