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.

Here is how to create a smart brightness-controlled lamp with motion sensor. It works only when the motion is detected and has two modes.

Make sure the adjustment knobs for sensitivity and on-time for the motion sensor are facing up so you can modify how sensitive your device is and how long it stays on to signal your Arduino.

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

Think of motion sensors, and your first thought probably goes to security. An intruder enters your property, the sensors detect them, and floodlights snap on. The same principle applies for ...

As for sensors, it has a light sensor and an optional 9-axis motion sensor, allowing for gesture sensing, proximity detection, and motion tracking.

If you can install a conventional outdoor light fixture, you can install a motion sensor light, although aiming and adjusting it takes extra effort.

Where are the best places to install indoor motion sensor lights? There are several spots within every home where sensor lights come into their own, many of which can be found in the kitchen.

Philips Hue motion sensor turns lights on for you All for the sake of convenience (and, let's be real, laziness).

Now, a team from Florida State University might have a partial answer to those first two problems, with a new class of motion sensor that could make wearables do more for less.
