Abstract

A switch that can turn on and off based on surrounding sound is proposed in this report. Not any sound can activate the switch but only high frequency of voice can trigger the switch. If the sound cannot be detected because of the distance or the surrounding noise, a wireless device will be used to transmit a modulated signal that carries a high pitch sound. The signal received will then be processed by the circuit to trigger any electrical equipment. A good frequency band must be chosen so that no electrical noise that can interferes the wireless signal andthe quality of the signal transmitted must be good. The developed prototype can be applied as home security applications or application to help some people, for example small children or disable people to switch onthe light and also to give a warning.
