| Residential use vacancy sensors |
The vacancy sensors use passive infrared technology to detect when a space becomes vacant. The switch operates by sensing the difference between infrared energy from a human being in motion and the background space. The switches provide manual-ON operation. Users can manually turn lights off after a space becomes vacant and a preset time delay elapses.
Until recently, most occupancy sensors were fully automatic, turning the lights on when someone entered the room and turning them off after they left. For areas where there in a significant amount of light from natural daylight or from spillover from adjacent areas, this can be wasteful as the sensor may be turning the lights on when the occupants might have chosen to leave them off. Now we can off units that are "off only" occupancy sensors, also known as vacancy sensors. This style of sensor offers the maximum of energy savings. |
