Claim 0:
1. A wireless industrial process monitor for monitoring an industrial process, comprising:
a controller configured to control operation of the industrial process monitor;
an ambient environment sensor configured to sense acoustic signals received from an ambient environment of the industrial process proximate the process monitor and responsively provide a sensor output signal, wherein the ambient environment sensor is an acoustic sensor configured to operate in a low power pilot mode at a first sampling rate and in a high power mode at a second sampling rate, wherein the first sampling rate is less than the second sampling rate;
a memory configured to store acoustic profile information comprising acoustic amplitude values at a plurality of frequencies;
wireless output circuitry configured to provide an output based upon the sensor output signal; and
wherein the controller causes the ambient environment sensor to enter a high power mode upon detection of an anomaly in the sensor output signal based upon a comparison of acoustic amplitude values at a plurality of frequencies in the sensor output with the acoustic amplitude values at the plurality of frequencies of the acoustic profile information stored in the memory.
