Method of calibrating a daylight sensor

摘要

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.
