To function correctly, it cycles between two temperatures: a high-temperature phase to \"clean\" the sensor and a low-temperature phase to \"detect\" the CO molecules.\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 the MQ-7 is a Life-Saving Essential:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• CO Specialization: It is tuned to be highly sensitive to Carbon Monoxide while ignoring common household gases like LPG or Methane that might trigger false alarms in other sensors.\u003cbr\u003e• Wide Detection Range: It can detect CO concentrations from 20 to 2000 ppm. Since human health issues begin at concentrations as low as 50–100 ppm, this sensor provides ample early warning.\u003cbr\u003e• Dual Output Utility:\u003cbr\u003e* Analog (A0): Provides a variable voltage proportional to the CO level. This is used to track \"ppm\" levels over time.\u003cbr\u003e* Digital (D0): Acts as an immediate threshold trigger. Using the onboard potentiometer, you can set a specific safety limit that, when crossed, instantly alerts a microcontroller.\u003cbr\u003e• Industrial and Domestic Versatility: It is robust enough for industrial monitoring but small and affordable enough for DIY home security projects.\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\u003eTechnical Capabilities:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Dual-Stage Heating:\u003cbr\u003e* High Heat (5V): For 60 seconds (cleans the sensor by evaporating accumulated gases).\u003cbr\u003e* Low Heat (1.5V): For 90 seconds (the actual measurement phase where CO is detected).\u003cbr\u003e• High Sensitivity: Capable of detecting very low concentrations of CO that are otherwise impossible for humans to sense.\u003cbr\u003e• Operating Voltage: 5V (standard for the module).\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-7 is the primary choice for domestic CO alarms, car cabin air quality monitors, industrial chimney monitoring, and portable safety devices for fire investigators or HVAC technicians.\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46404506878151,"sku":"TE-GASSE-070","price":105.93,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/MQ7_1.png?v=1776442841","url":"https:\/\/shop.tinkedge.tech\/products\/high-sensitivity-co-carbon-monoxide-sensor-detector-mq-7","provider":"TinkEdge","version":"1.0","type":"link"}
