Currents drawn during the active sensor state are substantially constant. During transition, currents decrease from the substantially constant current to a minimum current. During data transfer, currents vary between the substantially constant current and the minimum current. A logical element is configured to monitor the current drawn by the sensor module and, based on variations therein, determine the operating state of the sensor module. A method for using the processor is also disclosed.
