Description
The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high frequency signal that received from the microphone, and outputs a positive envelop. This will make for Arduino's signal acquisition. The output value depends on the level of sound input. In order to avoid unnecessary signal disturbances, input signal will go through two times filtering inside the module. Lastly, there is a screw potentiometer that enables manual adjustments to the output gain.
Features
Grove compatible interface
Wide supply voltage range
Built-in signal filtering
Gain adjustable via screw potentiometer
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

描述
格羅夫響度感應器旨在檢測環境聲音的響度。基於放大器 LM2904 和內置麥克風, 它放大和過濾從麥克風接收到的高頻信號, 並輸出一個正的信封。這將使 Arduino 的信號採集。輸出值取決於聲音輸入的級別。為了避免不必要的信號干擾, 輸入信號將在模組內進行兩次過濾。最後, 有一個螺絲電位器, 使手動調整的輸出增益。
功能
格羅夫相容介面
寬電源電壓範圍
內置信號過濾
通過螺釘電位器增益可調
