Abstract: The invention provides a wireless means of power monitoring and control of lighting fixtures. The device consists of five sections; line voltage AC to DC convertor and DC power circuit, voltage sensing circuit, current sensing circuit, relay circuit, and wireless microcontroller (“WUC”). Power input to the device is made via a multi-pronged connector (“MPC”). The AC to DC convertor reduces voltage to an acceptable level for the DC voltage circuit to power the circuitry on the printed circuit boards. A logic-controlled relay circuit provides on/off control of the light fixture outputting to the “Load” terminal of the MPC. Line voltage from the MPC enter current and voltage sensing circuits, continues through signal shaping circuits, and is provided to the WUC for processing. The two input signals are scaled and computed to provide power consumption values which are then transmitted wirelessly to a building automation control network.
