SparkFun Sound Detector 聲音感測器 原裝進口

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.

SparkFun Sound Detector 聲音感測器 原裝進口

SparkFun声音探测器是一款小巧且易于使用的音频感应板,具有三种不同的输出。声音探测器不仅提供音频输出,还提供声音存在的二进制指示,以及其振幅的模拟表示。 3个输出是同时且独立的,因此您可以一次使用任意数量的输出。

包络输出允许您通过简单地测量模拟电压轻松读取声音幅度。可以使用通孔电阻调节增益,以改变二进制(栅极)输出引脚的阈值。有关设置增益的更多信息,请查看下面的连接指南。

三个输出信号中的每一个都出现在电路板边缘的.1“标头上。它们同时活跃。如果您未在特定应用中使用,只需将该引脚断开即可。

Each of the three output signals is present on the .1″ header 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.
