{"product_id":"sound-sensor-module-blue","title":"SOUND SENSOR MODULE BLUE","description":"\u003cp\u003eSound detection sensor module (blue PCB) for Arduino. Detects sound intensity via microphone fed into an LM393 op-amp. Adjustable sensitivity potentiometer sets the threshold — output goes low and LED illuminates when sound exceeds the set level. Single-channel digital output compatible with 3.3–5V systems.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePCB Colour: Blue\u003c\/li\u003e\n\u003cli\u003eIC: LM393\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 3.3–5V DC\u003c\/li\u003e\n\u003cli\u003eOperating Current @ 5V: 4–8mA\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\u003eMicrophone Sensitivity @ 1kHz: −48 to −52dB\u003c\/li\u003e\n\u003cli\u003eOutput: Digital (high\/low)\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: −10 to +50°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eClap-activated switches and sound-triggered Arduino projects\u003c\/li\u003e\n\u003cli\u003eNoise threshold detection and alarms\u003c\/li\u003e\n\u003cli\u003eSound-responsive LED or relay control\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Powered by INFINITY WORKS","offers":[{"title":"Default Title","offer_id":47371695194166,"sku":"TW342","price":47.6,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9335\/5062\/files\/SOUND_SENSOR_MODULE_BLUE.jpg?v=1787646172","url":"https:\/\/tecwizdom.com\/products\/sound-sensor-module-blue","provider":"Tecwizdom.com","version":"1.0","type":"link"}
