Oct 10, 2016 · Photocells and motion sensors are electronic devices you can use to manage indoor or outdoor lighting. These sensors improve the security and safety of your home, automatically turning on lights when it gets dark or they detect motion. They also save energy by turning themselves off when extra light is unnecessary.

So, what exactly is the difference between a photocell and a motion sensor? While both photocells and motion sensors are designed to improve lighting efficiency, they work in distinct ways. A photocell detects changes in natural light levels, automatically turning lights on at dusk and off at dawn, making it ideal for areas that require ...

• The sensor uses a minor motion feature to detect small body movements which allows the lights to stay on when individuals in the space are nearly stationary. The major motion feature exhibits a lesser degree of sensitivity requiring larger movements. • Configuration is made using the Leviton Smart Sensor App from a smartphone or other ...

Motion Sensor Flood Light Outdoor, 20W Plug in Motion Sensor Light with 4.9ft Cord, IP66 Waterproof Floodlights with Photocell 6000K Super Bright Security Light for Garden Patio

Nov 15, 2016 · What Is A Photocell Sensor? A photocell sensor is an electrical device that hooks up and communicates with a transformer. Photocell sensors work like a timer switch in that they power light fixtures off and on automatically during a set “time”.

Photocells and motion sensors differ in the way they trigger lights to turn on. Photocells detect changes in light levels and react accordingly. Motion sensors respond to any physical movement within their range. Motion sensors can work one of two ways: Active sensors emit light or ultrasonic sound.

The differences between photocells and motion sensors offer many control options for indoor and outdoor lighting systems. Use a combination photocell and motion sensor to activate security lights around your home, but only after dark.

May 29, 2024 · Photocell lights provide automated, dusk-to-dawn lighting ideal for outdoor settings, while motion sensor lights offer efficient, on-demand lighting perfect for security and convenience. When choosing between the two, consider the specific requirements of your space and the primary function you need the lighting to serve.

Slim low profile sensor provides multi-level control based on motion and/or daylight. Sensor controls 0-10 VDC LED drivers. Rated for cold and wet locations (-30 degrees C to 70 degrees C). Two unique PIR lenses are available and used based on fixture mounting height.

Aug 11, 2023 · Photocells react to light changes, while motion sensors respond to movement (and the associated heat changes). Photocells are fabulous for outdoor spaces where daylight and nighttime cycles matter. Motion sensors shine in areas where movement detection is crucial, like hallways or security zones.
