MQ-3 Alcohol Detector Module which can sense the presence of Alcohol in the air. The module uses our MQ-3 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides an interface through standard 4 x 0.1″ header pins.\u003cbr\u003e\u003cbr\u003e\n\nIt provides an analog output corresponding to the concentration of the gas in the air and an easy to use digital output.\u003cbr\u003e\u003cbr\u003e\n\nThe onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered. Just power the module with 5V set the threshold and you can start getting the \u003cstrong\u003e gas concentration of the air around the sensor! \u003c\/strong\u003e An onboard LED signals the presence of any gas. Perfect sensing alcohol concentration on your breath just likes a common breathalyzer.\u003cbr\u003e\u003cbr\u003e\n\nThe digital output can be easily interfaced to microcontrollers and other circuits. The analog output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eType: Gas Sensor\u003c\/li\u003e\n    \u003cli\u003eVoltage: 5V\u003c\/li\u003e\n    \u003cli\u003eCurrent: 150mA\u003c\/li\u003e\n    \u003cli\u003eTemperature: -10℃ to +70℃\u003c\/li\u003e\n    \u003cli\u003eConcentration: 0.05 to 10 mg\/L Alcohol\u003c\/li\u003e\n    \u003cli\u003eLoad Resistance: 200 kΩ\u003c\/li\u003e\n    \u003cli\u003eDimensions: 36x20x16 mm\u003c\/li\u003e\n    \u003cli\u003eWeight: 5g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eSignal output light indicator\u003c\/li\u003e\n    \u003cli\u003eAnalog and level signal output\u003c\/li\u003e\n    \u003cli\u003eTTL output: Valid signal is low\u003c\/li\u003e\n    \u003cli\u003eHigh sensitivity to carbon monoxide\u003c\/li\u003e\n    \u003cli\u003eLong service life and reliable stability\u003c\/li\u003e\n    \u003cli\u003eFast response and recovery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eApplications :\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBreath Alcohol Testers:\u003c\/strong\u003e Used in devices for measuring blood alcohol concentration (BAC).\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eSafety Monitoring:\u003c\/strong\u003e Detects alcohol levels in industrial environments to ensure safety.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eAutomotive Safety Systems:\u003c\/strong\u003e Integrated into vehicles to monitor driver sobriety.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eSmart Devices:\u003c\/strong\u003e Utilized in IoT systems for alcohol detection and monitoring.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eEducational Projects:\u003c\/strong\u003e Ideal for DIY and academic applications in gas sensing studies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eIntegration with Arduino\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: center;\"\u003e\u003cimg alt=\"MQ-3 Sensor Module\" height=\"85%\" width=\"85%\" style=\"margin-bottom: 16px; float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/mq3-integration-with-arduino.jpg?v=1635763121\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eSample Code\u003c\/h3\u003e\n\u003cscript src=\"https:\/\/gist.github.com\/labsguru\/1e34604287d3cb3868d4f673176e1286.js\"\u003e\u003c\/script\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions: 36x20x16 mm\u003c\/li\u003e\n    \u003cli\u003eWeight: 5g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 x MQ-3 Alcohol Detector Gas Sensor Module\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":40708838588597,"sku":"KG052","price":122.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/MQ-3_Alcohol_Detector_Gas_Sensor_Module_1.jpg?v=1736594346","url":"https:\/\/kitsguru.com\/de\/products\/mq-3-sensor-module","provider":"KitsGuru","version":"1.0","type":"link"}
