General Description:
A sound sensor is a device that converts sound waves into electrical signals that can be processed by an electronic circuit. They can be used to detect and measure the frequency and amplitude of sound waves.
Working Principle:
The working principle of a sound sensor is based on the conversion of sound waves into an electrical signal. When sound waves strike a microphone, they cause the diaphragm to vibrate. This vibration generates an electrical signal that is proportional to the amplitude of the sound waves. This electrical signal is then sent to an electronic circuit for processing.
