List of evaluated light sensors Circuit Diagram These sensor lighting solutions use sensors to automatically control light intensity based on occupancy and ambient light levels, significantly reducing electricity waste. By ensuring lights are only on when needed, sensor lighting minimizes energy consumption, making it an ideal solution for both residential and commercial spaces Occupancy sensors must be located where they will detect occupants or occupant activity in all parts of the room. Ultrasonic sensors detect sound, while infrared sensors detect heat and motion. In addition to controlling ambient lighting in a room, they are useful for task lighting applications such as over kitchen counters. Estimating energy savings resulting from installation of more-efficient light fixtures and lighting systems is fairly straightforward, being based on the difference in wattage. however, can be challenging, as actual savings will depend on application characteristics such as occupant behavior, building design, site orientation, availability

An Applications Guide for Federal Facility Managers Lighting use constitutes about 20% of the total energy consumption in commercial buildings. Adding lighting controls is a simple retrofit option than can save on energy costs while help-ing to meet agency and federal energy savings mandates. Some energy codes and federal standards require the
By tapping into this phenomenon, light sensors can detect and measure light intensity, providing valuable data for energy-saving applications. 2. Photoconductive Effect. In photoconductive sensors, materials change their electrical resistance when exposed to light. Cadmium sulfide (CdS) cells, for example, become more conductive as light
