ABSTRACT

This project has been selected because of its applicability in our day to day and its potential to conserve power using locally assembled electronic components. The device sound activated switch functions by responding to sound of certain intensity (60decible); hand clap two to three meter away and finger tap at a very close range. This device contains a condense microphone at the input, where transduction of sound to electrical pulse takes place, which is coupled to a digital circuit realized with three cascased transistor which changes the input (analogue) to digital. The Dtype flip flop toggles to energize the electromagnetic relay at the output where the output load (max 200 watts) is interfaced.
