描述

SparkFun Sound Detector 聲音感測器模組 美國 SparkFun 原裝進口

SparkFun的聲音檢測器是一個小巧的,非常容易使用的音頻感應板,有三個不同的輸出。聲音檢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幅度的模擬表示。3個輸出是同時的和獨立的,所以你可以一次使用盡可能多的或盡可能少的。信封輸出使您可以通過簡單地測量模擬電壓輕鬆讀取聲音的幅度。增益可以通過通孔電阻進行調整,以改變二進制(門)輸出引腳的閾值。查看下面的連接指南,了解更多關於設置增益的信息。

三個輸出信號中的每一個都出現在電路板邊緣的“1”引腳上,它們同時工作,如果在特定的應用中沒有使用這個信號,只需將該引腳斷開即可。

SparkFun Sound Detector

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. Get Started with the SparkFun Sound Detector Guide
