While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Monoprice also sells a motion sensor, but that model is unable to trigger routines (only the Stitch contact sensor can), so you still need a hub if you want to use motion sensors in your home.

If your iPhone's sensors aren't working correctly, you may need to calibrate them. Here's how to calibrate an iPhone's brightness and motion sensors.

Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

HomeKit motion sensors are a vital accessory when building a smart home than runs by itself without manually turning devices on and off.

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

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 ...

Beyond just informing you whenever it detects motion, there are actually several creative ways to use motion sensors throughout the home.

Do you really need a stand-alone outdoor motion sensor when all of Ring’s outdoor lighting products have one built in?
