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.

A load control system may control an electrical load in a space of a building based on one or more parameters regarding the physical condition of an occupant. The parameters may be gathered by one or more sensing devices. The sensing devices may be included in a mobile device. A system controller may receive the parameters and may automatically control the electrical loads in response to the parameters. The system controller may control the electrical load to attempt to adjust the physical condition of the occupant in response to the sensed parameters. The system controller may control the electrical load to provide an alert, an alarm, and/or a warning in response to the sensed parameters.

Load control system responsive to sensors and mobile devices

A low-cost, simple ultrasonic sensing system has an increased detection range. The ultrasonic sensing system may be implemented as part of a load control system for controlling the power delivered from an AC power source to an electrical load. The load control system may comprise a load control device for controlling the power delivered to the electrical load, an ultrasonic receiver for receiving ultrasonic waves characterized by an ultrasonic frequency, and an ultrasonic transmitter located remotely from the ultrasonic receiver. The load control device controls the power delivered to the electrical load in response to the ultrasonic waves received by the ultrasonic receiver. The load control device may include the ultrasonic receiver and may be a wall-mounted load control device. The ultrasonic receiver may be a wireless ultrasonic receiver for transmitting wireless signals to the load control device in response to the ultrasonic waves received by the ultrasonic receiver.

A sensor adapted to be mounted to a surface has a rotatable enclosure that may be used, for example, to direct a lens of the sensor towards a window. The daylight sensor includes a photosensitive circuit for measuring a light intensity in the space, a cover portion, and a base portion adapted to be mounted to the surface. The cover portion is rotatable with respect to the base portion, for example, to direct the lens towards the window after the base portion is mounted to the surface. The base portion may also include a cylindrical wall having a channel adapted to capture a snap of the cover portion, such that the snap may move angularly through the channel to allow for rotation of the cover portion with respect to the base portion to a plurality of discrete positions.

A daylight sensor is adapted to be mounted to a surface in a space having a window, and has a rotatable enclosure for directing a lens of the daylight sensor towards the window. The daylight sensor includes a photosensitive circuit for measuring a light intensity in the space, and an enclosure for housing the photosensitive circuit. The lens directs light from the space towards the photosensitive circuit. The enclosure has a cover portion and a base portion adapted to be mounted to the surface. The cover portion is rotatable with respect to the base portion, so as to direct the lens towards the window after the base portion is mounted to the surface. The base portion may also include a cylindrical wall having a channel adapted to capture a snap of the cover portion, such that the snap may move angularly through the channel to allow for rotation of the cover portion with respect to the base portion.

Wireless sensor

A wireless lighting control system comprises a daylight sensor for measuring a light intensity in a space and a dimmer switch for controlling the amount of power delivered to a lighting load in response to the daylight sensor. For example, the daylight sensor may be able to transmit radio-frequency (RF) signals to the dimmer switch. The system provides methods of calibrating the daylight sensor that allow for automatically measuring and/or calculating one or more operational characteristics of the daylight sensor. One method of calibrating the daylight sensor comprises a 'single-button-press' calibration procedure during which a user is only required to actuate a calibration button of the daylight sensor once. In addition, the daylight sensor is operable to automatically measure the total light intensity in the space at night to determine the light intensity of only the electrical light generated by the lighting load.
