Arduino Sound Impact Sensor Unit - Analog Output


This sound impact sensor module uses LM386 IC and Electret condenser microphone as the main components.

The Audio AMP Board features an LM386 power amplifier designed for use in low-voltage consumption. The gain is set internally to 20 to keep external part count low and can be increased up to 200 by adding an external resistor and capacitor between pins 1 and 8.

This board is a great choice for AM/FM radio amplifiers, portable cassette player amplifiers, intercoms, TV sound systems and robots.


* Can detect the surrounding sound then output analog value.

* Can set a sound value then output digital value.
