In clean air, the conductivity is low. When flammable gases or smoke are present, the sensor's conductivity increases in proportion to the gas concentration.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cstrong\u003e\u003cbr\u003eWhy it’s a Safety System Essential:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Multi-Gas Detection: Instead of needing five different sensors, the MQ-2 acts as an all-in-one monitor for common household and industrial hazards like gas leaks (LPG\/Methane) and fires (Smoke\/CO).\u003cbr\u003e• Dual Output Mode: \u003cbr\u003e* Analog (A0): Provides a continuous voltage that tells you how much gas is present.\u003cbr\u003e* Digital (D0): Acts like a switch. When gas levels cross a certain limit, the pin flips from LOW to HIGH, which can instantly trigger a buzzer or fan.\u003cbr\u003e• Onboard Potentiometer: You can manually adjust the \"trip point\" for the digital output using a small screwdriver, allowing you to calibrate the sensitivity for your specific room environment.\u003cbr\u003e• Durability: These sensors are built for longevity and can operate for years in stationary safety devices.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cstrong\u003e\u003cbr\u003eTechnical Capabilities:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Detection Range: 300 to 10,000 ppm (parts per million).\u003cbr\u003e• Heating Voltage: Requires a steady 5V to power the internal heater.\u003cbr\u003e• Fast Response: Once warmed up, the sensor reacts to gas changes in less than 2 seconds.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cstrong\u003e\u003cbr\u003eBest For:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003eThe MQ-2 is the go-to sensor for home gas leak alarms, industrial smoke detectors, smart kitchen ventilation, and LPG cylinder monitoring.\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46397457268935,"sku":"TE-GASSE-065","price":147.66,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/MQ2_1.png?v=1776442450","url":"https:\/\/shop.tinkedge.tech\/products\/smoke-detection-mq-2","provider":"TinkEdge","version":"1.0","type":"link"}
