Single bit output Detection range: 3 meters Power requirements: 5 VDC Compatible with all Parallax microcontrollers 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. Features: Detection range up to 3 meters away On-board potentiometer provides an adjustable range of detection Single bit output 3-pin SIP header ready for breadboard or through-hole projects Built-in series resistor for compatibility with the Propeller microcontroller and other 3.3V devices Application ideas: Noise activated alarm systems Holiday animated props Monitoring systems
