Automatic system enabled daylight sensor

A daylight sensor system for a light fixture, the daylight sensor system comprising:

• a power circuit arranged to receive alternating current and to convert the received alternating current to direct current;
• a motion detector coupled to the power circuit;
• and
• a photodiode integrated circuit (PD IC) coupled to the power circuit;
• and
• a microcontroller coupled with the PD IC and with the motion detector;
• and
• a relay coupled with the microcontroller, wherein the microcontroller is configured to activate the relay upon receipt of an output from the PD IC that is indicative of a lux reading.

A method, comprising at a microcontroller of a lighting fixture:

• receiving outputs from a motion detector and a photodiode (PD) integrated circuit (IC);
• determining, using the received outputs from the motion detector, whether the microcontroller is in an active mode;
• receiving from the PD IC an output representing a lux reading in the vicinity of the PD IC;
• and
• determining based on the output received from the PD IC whether the microcontroller will activate or deactivate a relay.
