LM393 module has 3 pins which are Out, GND and VCC. GND is connected to the ground and VCC is connected to the positive terminal of the power supply. Out is an Output pin. Out pin is high when it does not detect any sound. It goes low whenever it detects sound in its surroundings. Out pin is connected to the digital pin of the microcontroller board or directly to a 5V relay. \u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-weight: 400;\"\u003eT\u003c\/span\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cspan style=\"font-weight: 400;\"\u003ehere is a potentiometer onboard to calibrate the digital output of the module. By potentiometer, a threshold volume can be set and when this threshold volume is exceeded status LED will light up and digital output will be low. The other LED glows when the device is powered.  This module can be used for Acoustic control light, give sound and light alarms working with Photosensitive sensors, sound control, sound detect and DIY projects like clap circuits. \u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-weight: 400;\"\u003eUses an electret condenser microphone\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eLM393 Op-Amp is used\u003c\/li\u003e\n\u003cli\u003eSignal Output indication\u003c\/li\u003e\n\u003cli\u003eBoth Analog and Digital Output are given\u003c\/li\u003e\n\u003cli\u003eThe comparator output is light\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003eElectric condenser microphone\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan class=\"a-list-item\"\u003eLow-level output signal used for sound control light\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h5\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eWorking voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eDC 3.3-5 V\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOp-Amp IC\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eLM393\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eInduction distance\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.5M\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBoard PCB Size\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e34 x 16 mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eOutput Type \u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBoth Analog and Digital\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eTrimpot Value\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e100k ohm \u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMicrophone Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eElectret Condensor Microphone\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"electronifyindia","offers":[{"title":"Default Title","offer_id":46643901858111,"sku":"PC01A","price":39.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/4628\/7167\/files\/LL39AAAAA.webp?v=1710312529","url":"https:\/\/www.electronifyindia.com\/products\/lm393-electret-microphone-module","provider":"ElectronifyIndia","version":"1.0","type":"link"}
