The main blocks are microcontroller unit, LCD display unit, microphone, valve circuit and voice signal processing circuit. Our project works according to the voice signal of the microphone. Here we tell you the required level of fuel (say 1 liter, 2 liters) to the micro controller through a transducer called a microphone. The microphone is one of the transducer device that converts incoming sound power in to electrical power, which is fed to the voice signal processing circuit to analyze the incoming frequency range. Thereafter the microcontroller unit is given to control the output valve circuit. The opening and closing mechanism of the output valve circuit depends on the speech signal, which is detected from the speech signal processing circuit. Here the LCD screen is connected to the microcontroller to show the required level of fuel that is the same as what we said through the microphone. So from the LCD we can find the fuel outlet, which is fed from the outlet valve.
