摘要： A load control system for controlling at least one electrical load may comprise a plurality of control devices and a sensor external to at least one of the control devices. The sensor may be configured to sense a condition of a space in which the control devices are installed. The at least one electrical load may be controlled in response to the condition sensed by the sensor. The control devices may include respective illuminated portions. The control devices may adjust the intensity of the respective illuminated portions in response to the condition sensed by the sensor. If multiple sensors are included in the load control system to sense the condition, the control devices may adjust the intensity of their respective illuminated portions by aggregating the condition sensed by each sensor.

摘要： A sensor for sensing environmental characteristics of a space may include a visible light sensing circuit for recording an image of the space and a control circuit responsive to the visible light sensing circuit. The control circuit may detect an occupancy or vacancy condition in the space in response to the visible light sensing circuit, and measure a light level in the space in response to the visible light sensing circuit. The control circuit may also include a low-energy occupancy sensing circuit for detecting an occupancy condition in the space. The control circuit may disable the visible light sensing circuit when the space is vacant. The control circuit may detect an occupancy condition in the space in response to the low-energy occupancy sensing circuit and subsequently enable the visible light sensing circuit. The visible light sensor may be configured in a way that protects the privacy of the occupants of the space.

摘要： A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.
