A transmitting device for wireless transmission of measured parameters comprising a microcontroller and pulse generating means connected to said microcontroller, said microcontroller being configured to receive at least one detection signal representative of at least one measured parameter value and being also configured to control said pulse generating means so that said pulse generating means generate at least one pulse position modulation (PPM) signal comprising information corresponding to said at least one measured parameter value, said transmitting device further comprising or being connectable to an antenna for the wireless transmission of said PPM signal, characterized in that said pulse generating means comprise an oscillator and a power amplifier connected to said oscillator in order to amplify the pulses output from said oscillator and to output said PPM signal, and in that said microcontroller is configured, for each pulse of said PPM signal to be generated, to activate only said oscillator for a first period of time T1 and then to activate also said power amplifier only for a second period of time T2 following said first period of time T1, said microcontroller being also configured to maintain deactivated said oscillator and said power amplifier outside the time interval defined by said first and second periods of time T1 and T2. |
