Abstract:
A system having a radio frequency identification (RFID) reader and at least one passive RFID sensor tag, the RFID reader sends a radio frequency interrogation signal from to the passive RFID sensor tag having a sensor that provides a sensor value. The RFID reader receives from the passive RFID tag a backscattered radio frequency signal carrying the sensor value. An interrogation rate of the sensor tag, an accuracy of interrogation and/or a power of the radio frequency interrogation signal transmitted to the sensor tag is controlled based on a statistical analysis of the multiple received sensor values, multiple interrogations and/or a signal-to-noise ratio.
