Summarizing a system for obtaining a measurement from a remote location comprises a wireless sensor configured to change its resonant frequency in proportion to at least one sensed parameter; and a reader configured to define a band of resonant frequency values, to optimize itself for operation based on said band, to transmit an excitation pulse at only a fixed frequency to said wireless sensor, to receive a signal from said wireless sensor in response to said excitation pulse, and to sample and hold said received signal. |
