Abstract
Disclosed is a circuit including a sensor, a battery and a reservoir capacitance, the sensor being configured to generate sensor data and the capacitance being provided by one or more discrete capacitors. A first circuit component is configured to drain current from the battery to the reservoir capacitor to store energy in the reservoir capacitor at a safe rate. The safe rate does not adversely affect the battery's life. A second circuit component is configured to generate a series of data packets including sensor data at particular time intervals. A third circuit component is configured to transmit the series of data packets with the stored energy of the reservoir capacitor so that the transmitting does not drain the reservoir capacitor of all stored energy.
