Voice Operated Fuel Injector
Abstract
Voice Operated Fuel Injector project aim is to inject fuel
by voice signal through embedded system
PROJECT DESCRIPTION
In our project the main blocks are micro controller unit,
LCD display unit, microphone, valve circuit and voice signal processing
circuit. Our project works according to voice signal from the microphone. Here
we tell the required level of fuel (say 1 liter, 2 liter) to micro controller
through a transducer called microphone.
We already know that microphone is one
of the transducer device it convert the incoming sound energy in to electrical
energy, which is fed to voice signal-processing circuit for analyzing the
incoming frequency range. After that it is given to micro controller unit for
controlling the output valve circuit.
The opening and closing time mechanism of output valve
circuit is depending on the voice signal, which is detected from the voice
signal processing circuit. Here LCD display is interfaced with micro controller
for display the required level of fuel that is same as what we told through the
microphone. So from the LCD display we can find the fuel output, which is fed
from output valve
