DFRobot Gravity: Analog Sound Sensor For Arduino

This is a new Analog Sound Sensor compatible with Arduino.  Sound Sensor is typically used in detecting the loudness in ambient, the Arduino can collect its output signal and actuate accordingly. You may use it to make some funny interactive works such as a "clap and buzz" to find your lost keys or remote control if you add a buzzer. This sensor works best with our Audio analyzer module.  

As one of our new version of breakout boards, we have improved the analog sound sensor in below:  

• Wide voltage range from 3.3V to 5V
• Standard assembling structure (two 3mm holes with multiple of 5cm as interval)
• Easily interfaces for analog or digital)
• Icons to simply illustrate sensor function 
• High-quality connector
• Immersion gold surface
