A motion sensor activates the light when it detects something moving within its field of view. Photocells work with a resistor that changes its conductivity based on how many photons are hitting it.

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.

Choose a location. Y ou can install motion sensor lights anywhere, but if you want them to provide security and not simply illuminate your path in the dark, place them high enough to be able to ...

Aqara makes a lot of smart products, but they made their bones as a brand that produces smart sensors. Today, they’re launching the new Motion and Light Sensor P2, which uses Thread and Matter ...

The sensor does have some limits. It can only detect motion up to about 16.5 feet away. And while Philips will give you the option of reducing that — that is, only turning on lights when motion ...

As with Philips, you add the motion sensor directly in the same app you use to control your Lightify light bulbs. Configuration is quick and simple, after which you gain access to a limited menu ...

Up to 12 motion sensors can be connected to a Philips Hue Bridge. During a recent demonstration, Philips had the motion sensor connected to several smart light bulbs in a New York City hotel room ...

A 120-degree field of view detects motion within a nine meter range, and with the new light sensor, the Eve Motion can detect motion and changes in lighting to activate ‌HomeKit‌ devices.
