The post details 3 simple sound activated relay switch circuits which can used as a module for any system that might be assigned to trigger by detecting some kind of sound pressure levelor simply applications such as a voice activated alarm security circuit.
Sound Activated Switch Circuit With Pcb Eleccircuit Com
Voice activated switch circuit diagram. In a noisy environment the switch is often triggered by noise or the activation sensitivity must be turned down. Input amplitude is sensitive down to 10mv and the output comparator can drive a relay or interface to micro. This circuit overcomes this weakness. A traditional vox circuit is unable to distinguish between voice and noise in the incoming signal. A traditional vox circuit is unable to distinguish between voice and noise in the incoming signal. This circuit uses an mc2830 to form a voice activated switch vox.

Siris there any circuit diagram u knowthat can turns the house light on when c clap sound is appears n remains constantn also turns d light off with any sound or a clapif u know about dis then plezz make for me circuit diagram for men send it to my e mail d. This circuit uses an mc2830 to form a voice activated switch vox. This circuit overcomes this weakness. 8 thoughts on sound activated switch ratnadeep march 3 2012. This circuit is a voice operated switch vox and designed for audio frequencies within a commercial telephone bandwidth of 100hz to 3000hz.
