{"product_id":"grove-sound-sensor-noise-detector","title":"Grove - Sound Sensor\/ Noise Detector","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGrove compatible interface\u003c\/li\u003e\n\u003cli\u003eWide supply voltage range\u003c\/li\u003e\n\u003cli\u003eBuilt-in signal filtering\u003c\/li\u003e\n\u003cli\u003eGain adjustable via screw potentiometer\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eProduct number: Seeed 101020063\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Wiki\u003c\/li\u003e\n\u003cli\u003ePreface - Getting Started\u003c\/li\u003e\n\u003cli\u003eIntroduction to Grove\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Seeed","offers":[{"title":"Default Title","offer_id":46375180402745,"sku":"vhc1787258017696","price":3.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0795\/9176\/8121\/files\/grove---sound-sensor-noise-detector_1.jpg?v=1787258026","url":"https:\/\/myoutfitstore.shop\/products\/grove-sound-sensor-noise-detector","provider":"My Store","version":"1.0","type":"link"}
