METHOD AND APPARATUS FOR ELECTRONIC STORING OF CALIBRATION/IDENTIFICATION DATA FOR A WIRELESS LINEAR PASSIVE SENSOR

摘要

A passive sensor arrangement comprising a plurality of sensors (6) for monitoring environmental parameters at a number of separate locations (5), each sensor (6) requiring individual calibration. An interrogation system (2) receives and analyses data from the sensor (5), and a memory (1) is associated with each sensor (6) for storing the individual calibration data its associated sensor. Each sensor position has a memory card slot associated with it such that calibration information carried on a memory card inserted into a particular slot is automatically associated with the sensor in that position. In this way, calibration information for the sensors can easily be updated when sensors are moved or replaced by simply moving the associated memory card into a different slot or replacing the memory card with a new one carrying the calibration data for the replacement sensor.
