Abstract
A wireless node, such as a sensor node or other suitable node, includes a supercapacitor having a charge and one or more photocells adapted to charge the supercapacitor responsive to ambient light. A microprocessor cooperates with a wireless transceiver to transmit a count of one or more wireless messages. The microprocessor determines the charge of the supercapacitor, determines an incremental charge of the supercapacitor resulting from the ambient light, and adjusts the count of the wireless messages as a function of the charge of the supercapacitor and the incremental charge. A power supply, including a boost regulator and a filter capacitor, powers the microprocessor and the wireless transmitter from the charge of the supercapacitor.
