{"product_id":"mq-2-combustible-gas-sensor-module","title":"MQ-2 Combustible Gas Sensor Module","description":"\u003cp data-start=\"65\" data-end=\"716\" class=\"PDq2pG_selectionAnchorContainer\"\u003eThe MQ-2 Combustible Gas Sensor Module is a semiconductor-based gas detection module designed to detect a wide range of flammable gases and smoke, including LPG, methane (CH₄), propane, hydrogen, alcohol vapors, carbon monoxide (CO), and smoke. Built around the MQ-2 gas sensor and an onboard LM393 voltage comparator, the module provides both analog (AO) and digital (DO) outputs for seamless integration with microcontrollers. The sensor uses a tin dioxide (SnO₂) sensing element whose conductivity increases in the presence of combustible gases, enabling reliable gas detection. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"718\" data-end=\"1396\"\u003eOperating from a 5V DC supply, the module features an adjustable sensitivity potentiometer that allows users to set the digital output threshold according to their application. It offers fast response, long operational life, and stable performance, making it ideal for gas leakage alarms, smoke detection systems, industrial safety equipment, smart home automation, environmental monitoring, and educational electronics projects. Compatible with Arduino, ESP32, STM32, Raspberry Pi (with ADC where required), PIC, AVR, and other microcontrollers, the MQ-2 module is one of the most widely used gas sensors for combustible gas detection.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"etycth\" data-start=\"1403\" data-end=\"1420\" class=\"PDq2pG_selectionAnchorContainer\"\u003eKey Features\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cul data-start=\"1422\" data-end=\"2031\"\u003e\n\u003cli data-section-id=\"15304ru\" data-start=\"1422\" data-end=\"1466\"\u003eBased on the MQ-2 semiconductor gas sensor\u003c\/li\u003e\n\u003cli data-section-id=\"n3haw\" data-start=\"1467\" data-end=\"1504\"\u003eDetects combustible gases and smoke\u003c\/li\u003e\n\u003cli data-section-id=\"195ajmf\" data-start=\"1505\" data-end=\"1588\"\u003eSensitive to LPG, methane, propane, hydrogen, alcohol, carbon monoxide, and smoke\u003c\/li\u003e\n\u003cli data-section-id=\"cxlwdf\" data-start=\"1589\" data-end=\"1622\"\u003eDual analog and digital outputs\u003c\/li\u003e\n\u003cli data-section-id=\"1fzwx90\" data-start=\"1623\" data-end=\"1658\"\u003eBuilt-in LM393 voltage comparator\u003c\/li\u003e\n\u003cli data-section-id=\"1c4pydy\" data-start=\"1659\" data-end=\"1711\"\u003eAdjustable sensitivity using onboard potentiometer\u003c\/li\u003e\n\u003cli data-section-id=\"17bagie\" data-start=\"1712\" data-end=\"1745\"\u003eFast response and recovery time\u003c\/li\u003e\n\u003cli data-section-id=\"112163y\" data-start=\"1746\" data-end=\"1779\"\u003eStable and reliable performance\u003c\/li\u003e\n\u003cli data-section-id=\"agelrw\" data-start=\"1780\" data-end=\"1803\"\u003eLong operational life\u003c\/li\u003e\n\u003cli data-section-id=\"1t5ocfw\" data-start=\"1804\" data-end=\"1837\"\u003ePower and output indicator LEDs\u003c\/li\u003e\n\u003cli data-section-id=\"1am9i8h\" data-start=\"1838\" data-end=\"1859\"\u003eOperates from 5V DC\u003c\/li\u003e\n\u003cli data-section-id=\"sw2w14\" data-start=\"1860\" data-end=\"1931\"\u003eEasy interface with Arduino, ESP32, STM32, Raspberry Pi, AVR, and PIC\u003c\/li\u003e\n\u003cli data-section-id=\"1dcbm6k\" data-start=\"1932\" data-end=\"1965\"\u003eCompact PCB with mounting holes\u003c\/li\u003e\n\u003cli data-section-id=\"19km08h\" data-start=\"1966\" data-end=\"2031\"\u003eIdeal for gas leakage alarms and safety monitoring applications\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Roboracter","offers":[{"title":"Default Title","offer_id":46748691759158,"sku":"Q4P607YCRV","price":119.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/0731\/2694\/files\/mq2-1.png?v=1783280053","url":"https:\/\/roboracter.in\/products\/mq-2-combustible-gas-sensor-module","provider":"Roboracter","version":"1.0","type":"link"}
