Disclosed is a temperature sensing device for sensing aircraft wheel brake temperature, the temperature sensing device comprising: a surface acoustic wave, SAW, sensor element with a resonant frequency within a frequency range between 175 megahertz and 190 megahertz at a predetermined temperature. The predetermined temperature range may be from 24 DegC to 1000 DegC, and the frequency range from 176 MHz to 188 Mhz. Also disclosed is a temperature sensing system comprising the temperature sensing device and a wireless relay device for delivering an interrogation signal for wirelessly interrogating the SAW sensor element. The interrogation signal may scan frequencies within the frequency range. Also disclosed are a method for sensing temperature of a wheel brake of an aircraft, and an aircraft comprising the temperature sensing system. The frequency range does not overlap with, and is not close to, aircraft band frequencies. Consequently, no interference occurs between the signals sent and received by the temperature sensing device and radio communications in the aircraft band.
