Smart Control Technology (Building automation and lighting control solutions) helps reduce energy usage and cost by eliminating over-illumination and unnecessary waste. The solution provides centralised control of all lighting within a home or commercial building, allowing easy implementation of scheduling, occupancy control, daylight harvesting and more. The system automatically dims or turns off lights to take advantage of DR incentives and cost savings. The system can utilise occupancy sensing, ultrasonic sensing or a combination of the two.
Occupancy sensors monitor the area and control lighting when motion from either vehicles, people, or animals is detected. When motion can no longer be detected within one of the zones, the lights shut off. Passive infrared sensors react to changes in heat, such as the pattern created by a moving person. The control must have an unobstructed view of the building area being scanned. Doors, partitions, stairways, etc. will block motion detection and reduce its effectiveness. The best applications for passive infrared occupancy sensors are open spaces with a clear view of the area being scanned.
Ultrasonic sensors transmit sound above the range of human hearing and monitor the time it takes for the sound waves to return. A break in the pattern caused by any motion in the area triggers the lights. Ultrasonic sensors can see around obstructions and are best for areas with cabinets and shelving, restrooms and open areas requiring 360-degree coverage
A number of other devices connected to the Smart Lighting Control can automatically turn off lighting and other equipment based on their detection of motion in a specific area. Originally developed for security systems, occupancy sensors have since been engineered to control not only lighting but also HVAC systems for commercial spaces. These devices have grown more common recently as energy management has become a priority. For example, the typical office uses 29% of its electricity for lighting. Occupancy sensors can reduce this use by half.
