Abstract
An efficient sensing system. The efficient sensing system includes a first mechanism for sensing and a second mechanism for sensing. A third mechanism selectively polls the second mechanism upon receipt of a signal from the first mechanism. In a specific embodiment, the first mechanism includes an early warning sensor, and the second mechanism includes an accurate sensor. In the specific embodiment, the third mechanism includes a controller in communication with the accurate sensor and the early warning sensor. The controller samples the accurate sensor at the sampling rate in response to the signal.
