• What is it?

The Sound Sensor listens to the sound around it. You can use it to visualize the sound level or as a sound trigger to control your circuit.


• How it works?

The Sound Sensor is a simple microphone. It measures the noises nearby and converts the sound waves to electrical signals. When the noise is lower than a certain level, which is called the LOW Threshold’, the sensor detects a ‘QUIET environment’. When the noise is above a ‘HIGH Threshold’, it detects a ‘LOUD environment’.

Try to use the LOW/HIGH Threshold to trigger events like display the an ‘unhappy face’ on LED matrix when the environment is ‘Loud’.
