A tire pressure monitoring device for a wheeled vehicle that is capable of detecting vehicle motion from the output of a pressure sensor. The device determines from the output signal an indication of the power of the signal, for example the variance of the signal, and detects if the vehicle is stationary or in motion depending on the determined indication of power. The device may determine that the vehicle is in motion if the determined indication of power exceeds a threshold value.
