Abstract: This invention is directed to a measurement sensor comprising a radio frequency identification circuit for measuring a parameter. The circuit comprises at least of one component in which a characteristic of that component can be changed to reflect a change in a measured parameter, such that the frequency of the sensor varies according to changes in the measured parameter. The invention extends to a system for measuring a variable parameter that incorporates such a sensor.
