ABSTRACT:
A system is provided for automatically controlling a light level of an interior space. The system may include a light sensor, a transmitter, and a lighting system. The light sensor measures a light level of an interior space and sends the measured light level to the transmitter. The transmitter is in electrical communication with the light sensor. The transmitter is configured to receive the measured light level from the light sensor; to compare the received light level with a light level setting; to determine a value for a lighting indicator based on the comparison; to define a control signal including the determined value; and to send the defined control signal to a first receiver. The lighting system may include a light fixture and a second receiver mounted on the light fixture. The second receiver is configured to receive the control signal, to extract the determined value from the received control signal, and to adjust a light level of the light fixture based on the extracted value.
