Given the amount of energy in a sound wave and the microphone's capacity what you get is an extremely low signal that would not be enough (<20mV) to provide a reading from the Arduino. The sensor has a current-to-frequency converter that converts the photodiodes’ readings into a square wave with a frequency that is proportional to the light intensity of the chosen color. First, the sensor unit at the front of the module which measures the area physically and sends an analog signal to the second unit, the amplifier. It gives a measurement of how loud a sound is. In the graph above, the sensor is loaded with a 1Mω resistor and connected to an Arduino ADC. You could potentially use this sensor to turn a light on in your house after recognising a specific clap/whistle sequence.
