Grove - Sound Sensor can detect the sound intensity of the environment. The main component of the module is a simple microphone, which is based on the LM386 amplifier and an electret microphone. This module's output is analog and can be easily sampled and tested by a Seeeduino.

Features

  • Easy to use
  • Provides analog output signal
  • Easily integrates with Logic modules on the input side of Grove circuits

!!!Warning This sound sensor is used to detect whether there's sound surround or not, please don't use the module to collect sound signal. For example, you can use it to make a sound control lamp, but not as a recording device.

!!!Tip More details about Grove modules please refer to Grove System

Platforms Supported

Arduino Raspberry Pi BeagleBone Wio LinkIt ONE

!!!Caution The platforms mentioned above as supported is/are an indication of the module's hardware or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Getting Started

!!!Note If this is the first time you work with Arduino, we firmly recommend you to see Getting Started with Arduino before the start.

  • Step 2. Connect Grove-Sound Sensor to port A0 of Grove-Base Shield.
  • Step 3. Plug Grove - Base Shield into Seeeduino.
  • Step 4. Connect Seeeduino to PC via a USB cable.

!!!Note If we don't have Grove Base Shield, We also can directly connect Grove-LED Bar to Seeeduino as below.

A1 White
A0 Yellow

Software

  • Step 1. Please copy below code to Arduio IDE and upload to arduino. If you do not know how to upload the code, please check how to upload code.
// test code for Grove - Sound Sensor
// loovee @ 2016-8-30

const int pinAdc = A0;

void setup()
{
    Serial.begin(115200);
    //Serial.println("Grove - Sound Sensor Test...");
}

void loop()
{
    long sum = 0;
    for(int i=0; i<32; i++)
    {
        sum += analogRead(pinAdc);
    }

    sum >>= 5;

    Serial.println(sum);
    delay(10);
}
  • Step 2. Click on Serial > Plotter to get the changing curve of the sensor. Please make a noise to view the change of the value.
