Indoor lighting controls, also called occupancy sensors, are able to detect activity within a certain area. They provide convenience by turning lights on automatically when someone enters a room. They reduce lighting energy use by turning lights off soon after the last occupant has left the room.
Location is important when installing these sensors. Occupancy sensors must be located where they will detect occupants or occupant activity in all parts of the room. Locating a sensor in an obscure corner of the room that rarely has traffic would not contribute to a cost savings in energy.
There are two types of occupancy sensors: ultrasonic and infrared. Ultrasonic sensors detect sound, while infrared sensors detect heat and motion. For instance, if you were used to waking up to a stereo turned up to full volume, the ultrasonic sensor would add to your wake-up pleasure by turning on the lights automatically for you also. On the other hand, infrared sensors are helpful to install as a deterrent to thieves. Even though they may be stealthily quiet, once they enter a room and move around, the infrared sensor will know they are present and illuminate their work in progress!
In addition to controlling ambient lighting in a room, they are useful for task lighting applications, such as over kitchen counters. In such applications, task lights are turned on by the motion of a person washing dishes, for instance, and automatically turn off a few minutes after the person stops.
Consider functionality of your home and the lighting zones within each room. It is possible to save energy by using occupancy sensors throughout your living environment. Witt Electric can offer suggestions and solutions for all your home lighting needs.
