First Claim
Patent Images
1. A lighting control system for controlling at least one light circuit in a room, comprising:
- a first sensor; and
a second sensor coupled to said first sensor with a line voltage communication link;
wherein said first sensor and said second sensor act together to provide power to at least one light circuit upon detection of occupancy in an area by either of said sensors.

Abstract
There is disclosed a sensor which, when integrated into a dimming system, can turn the dimmer on and off, and vice versa. As an example, lights which are connected to the dimmer can be turned on by using the dimmer, the light level can be adjusted to provide a level of illumination desired by an occupant, and the sensor can turn off the lights when the room is vacant. The sensor here disclosed provides sensing functionality to a dimming system, and the sensors can be remotely controlled by other sensors, dimmers and dimmer remotes.
