Parallax Sound Impact Sensor

The Parallax Sound Impact Sensor detects sound from up to 3 meters away, lending noise-activation possibilities to your project. This sensor also includes an on-board potentiometer for easy adjustment of the range of detection for the sensor. This sensor is compatible with all Parallax microcontrollers. The sample code for both the BASIC Stamp 2 and the Propeller chip can be found in useful link tab.
