ABSTRACT:
To provide an electronic device starter that does not waste electric power while it is not being used and a vehicle tire monitoring system in which the starter is used for eliminating waste of electric power of batteries for its detectors. In a vehicle tire monitoring system according to the present invention, a monitor unit sends a start signal at time intervals T1by using an electromagnetic wave, a rectifier circuit33in a detector3which received the start signal converts a high-frequency electromotive force caused by the start signal at an antenna31into electric energy, this electric energy operates a central processing section34,a detector section35,and a transmitting section36,the central processing section34which started operating places an FET382in the on state to supply electric power from a battery381to a sensor section37to operate the sensor section37.
