The Sound Impact Sensor detects sound from up to 3 meters away, lending noise-activation possibilities to your microcontroller projects
Use a 2.2 k-ohm resistor (red-red-red) between the Sound Impact Sensor's SIG pin and the Propeller I/O pin.
Using the connections shown in the wiring diagram above, this example will display "Sound detected!" if the sensor detects one or more sound events, and "No sound detected." otherwise.
