Lighting Sensors & Controls
Occupancy sensors provide energy savings by ensuring lights are off when rooms are unoccupied. Often, the lights in stairwells, hallways, lobbies, and storage areas are left on around the clock, even during off-peak hours or at night. These sensors help reduce operating costs and save energy in these “back of house” spaces by ensuring that the lights are off when the space is vacant through occupancy sensing.
The daylight sensor is designed specifically to work with ballasts, control modules, and sensor interfaces to implement daylight harvesting. It allows the control system to automatically dim the lights when the available daylight is high and brighten the lights when the available daylight is low, in order to maintain a specific light level in the space. An integrated IR receiver resides within the sensor to allow access to the system for advanced programming and personal control. It receives an IR signal and transfers it to digital ballast. Its photopic response matches the human eye, and can be calibrated for daylight sensitivity through the lighting control system to which it is attached.
