1. A wireless sensor reader comprising:

  • an antenna for transmitting a plurality of excitation pulses to a wireless sensor;

    at least one receiver for receiving a ring signal from said wireless sensor in response to said excitation pulses, said receiver including at least one filter to filter said ring signal received from said wireless sensor,wherein said filter defines a passband window to allow a frequency bandwidth to be received by the reader,wherein said passband window may be defined to pass only a frequency band that corresponds to a parametric range, andwherein an ambient pressure sensor is in communication with said filter to at least partially define the passband window of a resonant frequency value to optimize itself for operation based on said passband window.
