Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

If you’ve always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your ...

Motion detectors currently on the market for smart homes are often a bit clunky. They detect movement but can’t distinguish specific areas and trigger devices related to them. The Aqara FP2 changes ...

If you’ve got an existing smart home rig, motion sensors can be a useful addition to your setup. You can use them for all ...

Need a cheap and easy way to deter intruders? For homeowners, outdoor lighting is a game changer for providing a line of sight on potential trepassers without running up costly energy bills. If you're ...

The Hue Outdoor Sensor is the first outdoor HomeKit sensor, and adds motion, temperature, and light sensors to automate the outside of your Apple-centric smart home. Recently, we took a look at the ...
