When methane is present in the air, the sensor's conductivity increases. This change is converted into a voltage signal that your microcontroller can interpret to determine the gas concentration in parts per million (ppm).\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eWhy it’s the Standard for Natural Gas Safety:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Methane Specificity: The MQ-4 is \"tuned\" for Methane. This reduces false alarms in environments where other vapours (like cooking smells or cleaning alcohol) might be present, making it much more reliable for home gas-leak detectors.\u003cbr\u003e• Wide Detection Range: It can detect concentrations from 200 ppm to 10,000 ppm. This allows it to identify a small leak long before it reaches the Lower Explosive Limit (LEL), providing a critical window for safety alerts.\u003cbr\u003e• Dual Output Utility: \u003cbr\u003e* Analog (A0): Provides a variable voltage (0V to 5V) that correlates to the concentration of gas. This is essential for monitoring if a leak is getting worse over time.\u003cbr\u003e* Digital (D0): Can be used as a simple \"on\/off\" switch to trigger an emergency exhaust fan or a siren if a pre-set safety limit is breached.\u003cbr\u003e• Adjustable Sensitivity: The onboard potentiometer lets you calibrate the digital \"trigger\" point. You can set it to be highly sensitive for industrial pipelines or more relaxed for a household kitchen.\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• Operating Voltage: 5V (Essential for the internal heater).\u003cbr\u003e• Power Consumption: ~150mA (Ensure your power supply can handle the heater's current draw).\u003cbr\u003e• Stability: Once the \"burn-in\" and preheat phases are complete, the sensor provides a very stable baseline for continuous monitoring.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003eThe MQ-4 is the go-to component for domestic gas leakage alarms, industrial methane monitoring, CNG vehicle safety systems, and smart city environmental sensors.\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46404506353863,"sku":"TE-GASSE-067","price":100.58,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/MQ4_1.png?v=1776442669","url":"https:\/\/shop.tinkedge.tech\/products\/methane-natural-gas-sensor-mq-4","provider":"TinkEdge","version":"1.0","type":"link"}
