A sensor assembly providing a physical property of a vehicle, e.g. tire pressure of a wheel of an aircraft, comprises electronic circuitry including a locking arrangement and sensor suited to sense the physical property and an exhaustable power source, e.g. a battery. For prolonged shelf life, a first and a second switch are functionally arranged between power source and circuitry. The second switch is controlled by the locking arrangement, whereas the first switch is controllable from outside the sensor assembly, e.g. by a magnetic field. The first switch is arranged to switch the power to the electronic circuitry, whereby the locking arrangement is powered, too. In consequence, the locking arrangement is capable to close the second switch. Thereafter, a further stimulus to the first switch will no more be capable to switch the sensor off, unless the locking arrangement enables it again by opening the second switch.
