Sensors & Photocells

While timers can be convenient in automatically turning on and of lights at specified times, sometimes the amount of light has nothing to do with the time of day. Sunset and sunrise times are different for each day and each location, and this may make sensors and photocells much more appropriate for your needs. These devices have sensors to detect the amount of light around it, and it can then turn on or off your light when a certain level of light is reached.

These devices can also be used indoors, where the time of day may not have anything to do with the level of light. For example, a room may be dark due to closed curtains and doors, and the sensors can activate lights in this case even at high noon. At night, it can turn off the lights to which it is connected if there is already sufficient illumination in the room.

While these sensors can be sturdy and simple enough to use—it’s basically a “plug and play” device—you may want to check and clean the sensors periodically. Dirt and grime may cover the sensors and let it think that it’s always dark. This will result in your light permanently turned on.
