A tyre pressure sensor device 122 for a wheel 112 of an aircraft (102, Fig.1) where the device includes a pressure sensor 124 for measuring the internal pressure of a tyre, a temperature sensor 126 for measuring a temperature local to the tyre, a memory unit 131 local to the tyre for storing data, and a control unit 128 local to the tyre arranged to record in the memory unit data in respect of multiple readings over time. The data recorded for each reading includes an indication of the time of the reading, the pressure as measured by the pressure sensor and the temperature as measured by the temperature sensor. Multiple successive measurements may be taken and recorded over time, both when the aircraft is on the ground and when the aircraft is in flight. Data may be uploaded to a portable handheld device 140, for example, for analysis when maintaining the tyres in their correctly inflated state. The device may comprise a motion sensor 134 used to determine when the aircraft is on the ground or in flight.
