Grove - Loudness Sensor 噪音感測器 環境聲音檢測模組 模擬輸出
Grove - Loudness Sensor 噪音感測器設計用於檢測環境聲音的響度。基於放大器 LM2904和內置麥克風，它放大並過濾從麥克風接收到的高頻信號，並輸出一個正信號。這將使 Arduino 的信號採集。輸出值取決於聲音輸入的水平。為了避免不必要的信號干擾，輸入信號將在模組內部經過兩次濾波。最後，有一個螺絲電位器，可以手動調整輸出增益。

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
