A pressure and temperature sensing device (1) for tires, particularly for cars, motorcycles and the like, comprising: sensing means (3, 4, 5, 6), which are adapted to detect the pressure and temperature of the tire to which the sensing device is connected; power supply means (2), which are adapted to supply power to the sensing means; at least one microcontroller (7), which is adapted to be supplied by the sensing means (3, 4, 5, 6) and to drive a radiofrequency circuit (8) for transmitting data that arrive from the sensing means to an electronic control unit arranged on board the vehicle; and receiver means (10) adapted to receive an electromagnetic signal and to activate the at least one microcontroller (7), the receiver means being passive, so as to not absorb energy of the power supply means.
