{"product_id":"pl4-sen-12642","title":"Sound Detector","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\n \u003cp\u003eThe 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.\u003c\/p\u003e\n\n \u003cp\u003eEach of the three output signals is present on the .1\" pin-out at the edge of the board. They are active simultaneously. If you arent using one in your particular application, simply leave that pin disconnected.\u003cbr\u003e\n \u003cbr\u003e\n-\u0026gt;\u003c\/p\u003e","brand":"SparkFun","offers":[{"title":"Default Title","offer_id":39690154148021,"sku":"PL4-SEN-12642","price":47.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/12642-01.jpg?v=1618122176","url":"https:\/\/getcahits.com\/products\/pl4-sen-12642","provider":"PuriLite","version":"1.0","type":"link"}
