The Grove Sound Sensor is a high - performance device that acts as a simple microphone. Built on the power amplifier LM386 and an electret microphone, it effectively detects the sound strength in the environment. You can easily adjust the output value using the potentiometer. This sensor comes with a Grove - compatible interface, making it convenient to use. It has a wide supply voltage range of 4V - 12V and a low quiescent current drain of only 4mA. The 2.0cm x 2.0cm twig module design requires minimal external parts. Ideal for simple microphone use and sound detection applications. For Grove users, especially beginners, we offer guidance PDF documents. Visit our wiki page for more product information.

Using the Grove Sound Sensor is easy. First, connect it to your device through the Grove - compatible interface. Make sure your power supply voltage is within the 4V - 12V range. Once connected, you can use it as a simple microphone or for sound detection. To adjust the output value, turn the potentiometer. When using, avoid exposing it to extremely high - volume sounds for a long time as it may affect its performance. For maintenance, keep it in a dry and clean environment.
