SparkFun Sound Detector 聲音感測器 原裝進口

SparkFun聲音探測器是一款小巧且易於使用的音頻感應板,具有三種不同的輸出。聲音探測器不僅提供音頻輸出,還提供聲音存在的二進制指示,以及其振幅的模擬表示。3個輸出是同時且獨立的,因此您可以一次使用任意數量的輸出。

包絡輸出允許您通過簡單地測量模擬電壓輕鬆讀取聲音幅度。可以使用通孔電阻調節增益,以改變二進制(柵極)輸出引腳的閾值。有關設置增益的更多信息,請查看下面的連接指南。

三個輸出信號中的每一個都出現在電路板邊緣的.1“引腳輸出端。它們同時處於活動狀態。如果您在特定應用中沒有使用它,只需將該引腳斷開即可

=========================================================

 

The SparkFun Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once.

The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted with a through-hole resistor, to change the threshold of the binary (gate) output pin as well. Check the hookup guide below for more information about setting gain.

Each of the three output signals is present on the .1″ pin-out at the edge of the board. They are active simultaneously. If you aren’t using one in your particular application, simply leave that pin disconnected.
