Description

Automation makes a person’s day-to-day tasks easy by reducing human effort. One such device which can do this is clap switches. These switches can be used even for security purpose. A clap sound can be used as a triggering signal either to switch relays on or off, or as an alert signal. This device can be realized by designing a circuit that activates or deactivates a relay, to which a lamp is connected, by a clapping system. The basic motivation of the project is to develop a product which will make a person’s life simpler, say to turn ON a particular device or an appliance by clapping, rather than the customary practice of switching ON the device using a switch, thereby reducing the human effort. In case of an emergency, a clap switch can be used as an emergency alert device as it can be a very quick way of signalling an alert.

Please Check attached doccument for more details (including oscilloscope measurements). Attached video is a demonstration of the project.
