{"product_id":"microphone-sound-detection-sensor-module","title":"Microphone Sound Detection Sensor Module","description":"\u003cp\u003e\u003cspan\u003eThe sound detection sensor module for Arduino detects whether the sound has exceeded a threshold value. Sound is detected via microphone and fed into an LM393 op-amp. The sound level set point is adjusted via an onboard potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eOperating voltage 3.3V-5V\u003c\/li\u003e\n\u003cli\u003eOutputs digital switching output (high and low levels 0 and 1\u003c\/li\u003e\n\u003cli\u003eOperating current (Vcc=5V): 4-8mA\u003c\/li\u003e\n\u003cli\u003eMicrophone sensitivity (1Khz): 52-48dB\u003c\/li\u003e\n\u003cli\u003eMicrophone Impedance: 2.2KΩ\u003c\/li\u003e\n\u003cli\u003eMicrophone Frequency: 16-20Khz\u003c\/li\u003e\n\u003cli\u003eMicrophone S\/N ratio: 54dB\u003c\/li\u003e\n\u003cli\u003eSignal output indication\u003c\/li\u003e\n\u003cli\u003eSingle-channel signal output\u003c\/li\u003e\n\u003cli\u003eOutputs low level and the signal light when there is sound\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch4\u003e\u003cstrong\u003ePackage Includes: \u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e1 x Microphone Sound Detection Sensor Module\u003c\/p\u003e","brand":"Indian Hobby Center","offers":[{"title":"Default Title","offer_id":43050120675371,"sku":"2622","price":55.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/microphone-sound-sensor-module-voice-sensor-high-sensitivity-sound-detection-module-whistle-module-550x550.webp?v=1770025700","url":"https:\/\/www.indianhobbycenter.com\/products\/microphone-sound-detection-sensor-module","provider":"Indian Hobby Center","version":"1.0","type":"link"}
