The document outlines a project on a clap switch device designed by students from Kit's College of Engineering, Kolhapur, aimed at providing an inexpensive, phono-controlled switch for various applications. Key components include a prototyping board, IC 4017, microphones, relays, and a total estimated cost of 140-150 INR. The device offers advantages such as energy efficiency, reliability, and safety for elderly or mobility-impaired individuals, with potential future improvements to enhance sensitivity and filtering capabilities.

DEVICE

17. ADVANTAGES
• 1. Energy efficient
• 2. Low cost and reliable circuit
• 3. Complete elimination of manpower
• 4. High Accuracy

18. APPLICATIONS
• Can turn something (e.g a lamp) on and off
from any location in the room simply by
clapping your hands.
• The primary application involves an elderly or
mobility- impaired person.
• It is generally used for a light, television, radio
or similar electronic device.

19. FUTURE SCOPE
• No filter has been used here so the switch will
respond to two sounds similar to clapping .
But if a simple bandpass filter is used then this
problem could be avoided.
• To add more sensitivity to the switch, the
amplification factor may be increased.

20. MARKET SURVEY

21. Summary
This device is helpful for:-
• If you wish to “ON” and “OFF” the device without
moving from your place.
• There is no fear of the electrical shocks as you are
not required to touch any of the mechanical
switches physically.
• Visual indication of the devices is also provided to
you.
• Speed of the fan can also be controlled by
connecting regulator with individual outputs.
