Lighting occupancy sensors save energy and money by detecting activity in work areas and automatically turning lights on when people enter a room and off when people have left.
Used properly, occupancy sensors can be a cost-effective way to reduce the operating time of lighting systems, resulting in outstanding energy savings.
Occupancy sensors are most effective in spaces that are frequently unoccupied, including offices, warehouses, storerooms, restrooms, loading docks, corridors, stairwells, office lounges and conference rooms.
Savings are made by ensuring that lighting is only energised when required.
Example Picture Provide light when and where it is required – an egress path for late night workers eliminates unnecessary energy usage after hours.
Estimates average saving potential for different space types using occupancy sensors
Passive Infrared (PIR) Occupancy Sensors and its working conditions
Infrared sensors detect the difference in heat emitted by humans in motion from heat emitted by the background space.
The sensitivity of PIR sensors to small movements decreases at distances greater than 15 feet.
They require a direct line of sight to sense motion.
The sensor’s field of view can be adjusted and should not be directed toward an open door where it may pick up people who are passing the doorway, but not entering the room.
Ultrasonic Occupancy Sensors and its working conditions
Ultrasonic sensors emit a high-frequency signal that is undetectable by humans and animals. This signal bounces off objects, surfaces and people in a space. It then returns to the sensor, which interprets change in the frequency as motion.
Ultrasonic sensors are highly sensitive to small movements up to 25 feet.
They typically offer a larger coverage area than PIR sensors, but should not be mounted in high ceiling applications (over 14 feet).
They may be prone to false triggering if placed too close to an HVAC vent.
Dual-technology sensors employ both PIR and ultrasonic technologies for maximum coverage and reliability with fewer false triggers.
It take advantage of the PIR units' resistance to false triggering and the sensitivity of ultrasonics.
These sensors activate light sonly when both technologies detect movement, and because either of the two technologies is enough to hold the lights on, these sensors significantly reduce the possibility of false on and off triggers.
Occupancy sensor based lighting control by BLAZE
A sophisticated lighting control system can provide significant cost savings in any environment from office towers to scientific laboratories, to sports field and stadiums. The BLAZE energy management solution is a building block approach – start with basic on/off control and incorporate dimming, time based control and powerful monitoring and reporting solutions to provide the ultimate in energy conservation.
Normally savings in energy usage of about 40% can be obtained from the installation of occupancy sensor based lighting. Product and installation can normally be financed from savings achieved in only a few years. All you will notice is an immediate reduction in your bills.
This sensors can be integrated to Blaze automation software by which one can control and monitor lighting system of home, office or building space etc.
