{"product_id":"waveshare-sound-sensor","title":"Waveshare Sound Sensor","description":"\u003cp\u003eThis is a Waveshare Sound Sensor. LM386 is an audio power amplifier with features of low power consumption, adjustable voltage gain, wide voltage power supply, fewer requirements on peripheral components, and minimum total harmonic distortion. LM386 can be applied to consumer products with low voltage requirements. To minimize the number of peripheral components used, the voltage gain should be set to 20.\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/robu-prod-media.s3.ap-south-1.amazonaws.com\/product-descriptions\/2021\/04\/Waveshare-Sound-Sensor.jpg\"\u003e\u003cimg class=\"wp-image-971363\" src=\"https:\/\/robu-prod-media.s3.ap-south-1.amazonaws.com\/product-descriptions\/2021\/04\/Waveshare-Sound-Sensor-300x152.jpg\" alt=\"Waveshare Sound Sensor\" width=\"444\" height=\"225\"\u003e\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eIn the case of working with an MCU: VCC ↔ 3.3V ~ 5.3V GND ↔ power supply ground AOUT ↔ MCU.IO (analog output) DOUT ↔ MCU.IO (digital output)\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003col\u003e\n\u003cli\u003eAudio amplifier\u003c\/li\u003e\n\u003cli\u003eAmbient sound detection\u003c\/li\u003e\n\u003cli\u003eSound level detection\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eOnboard audio power amplifier LM386\u003c\/li\u003e\n\u003cli\u003eAudio signal gain up to 200\u003c\/li\u003e\n\u003cli\u003eAdjustable accuracy\u003c\/li\u003e\n\u003cli\u003eSignal output indicator\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e1 x Sound Sensor\u003c\/p\u003e\n\u003cp\u003e1 x 4-pin custom connector jumper wire\u003c\/p\u003e\n\u003cp\u003eSpecification:\u003c\/p\u003e\n\u003ctable class=\"specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range (Hz):\u003c\/td\u003e\n\u003ctd\u003e50 to 20000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMic Sensitivity\u003c\/td\u003e\n\u003ctd\u003e52dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Hole Diameter (mm)\u003c\/td\u003e\n\u003ctd\u003eM2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength (mm):\u003c\/td\u003e\n\u003ctd\u003e34.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm):\u003c\/td\u003e\n\u003ctd\u003e18.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (g):\u003c\/td\u003e\n\u003ctd\u003e7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.007 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e4 × 2 × 1 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Jaideep Robotics","offers":[{"title":"Default Title","offer_id":46357465170093,"sku":"968470","price":281.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/7638\/9293\/files\/download-2026-06-21T165231.237.avif?v=1782040964","url":"https:\/\/jaideeprobotics.com\/products\/waveshare-sound-sensor","provider":"Jaideep Robotics ","version":"1.0","type":"link"}
