Its sensing element changes resistance according to the concentration of gas present, allowing the change to be measured through a suitable circuit. It is commonly used in gas leakage alarms, safety monitoring systems and portable gas detection equipment.\u003c\/p\u003e\n\u003ch3 data-pm-slice=\"1 1 []\"\u003e\u003cspan\u003eTechnical specifications:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSensor Type: Semiconductor Gas Sensor\u003c\/li\u003e\n\u003cli\u003eTarget Gases: Carbon Monoxide (CO) and Methane (CH₄)\u003c\/li\u003e\n\u003cli\u003eCO Detection Range: 10–500 ppm\u003c\/li\u003e\n\u003cli\u003eMethane Detection Range: 300–10,000 ppm\u003c\/li\u003e\n\u003cli\u003eHeater Voltage: 5.0V ±0.1V at high temperature \/ 1.5V ±0.1V at low temperature\u003c\/li\u003e\n\u003cli\u003eHeater Resistance: Approximately 29Ω ±3Ω at room temperature\u003c\/li\u003e\n\u003cli\u003eHeater Consumption: ≤900mW\u003c\/li\u003e\n\u003cli\u003eLoad Resistance: Adjustable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-pm-slice=\"1 1 []\"\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eGood sensitivity to carbon monoxide and methane\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eWide gas concentration detection range\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSimple interfacing circuit\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDurable metal mesh protective housing\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable for continuous gas-monitoring applications\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCompact through-hole design for PCB mounting\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCost-effective solution for gas detection systems\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-pm-slice=\"1 1 []\"\u003e\u003cspan\u003eApplications:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eCarbon monoxide leakage alarms\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDomestic gas safety systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIndustrial gas monitoring\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePortable gas detectors\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCombustible gas detection systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSafety and alarm projects\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMicrocontroller-based gas monitoring systems\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VISHA WORLD","offers":[{"title":"Default Title","offer_id":67605492924596,"sku":"VS00180","price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0527\/2692\/3444\/files\/MQ9GasSensor_2.png?v=1793085851","url":"https:\/\/vishaworld.com\/products\/mq9-gas-sensor","provider":"VISHA WORLD","version":"1.0","type":"link"}
