It has high sensitivity to Hydrogen (H2) and less sensitivity to alcohol, LPG, cooking fumes. Hydrogen gas is highly flammable and will burn in air at a very wide range of concentrations\u003c\/p\u003e\n\u003cp\u003eThe sensitivity is able to be adjusted by the potentiometer. The output is proportional to the density of the gas. You can use analog reading to read the data from this sensor.\u003c\/p\u003e\n\u003cp\u003eTo ease the difficulty of using this sensor,  a Gravity Interface is adapted to allow plug\u0026amp;play. The Arduino IO expansion shield is the best match for this senor connecting to your Arduino microcontroller\u003c\/p\u003e\n\u003cp\u003eWhat is Hydrogen? Hydrogen is a chemical element with chemical symbol H and atomic number 1.\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePower supply needs: 5V\u003c\/li\u003e\n\u003cli\u003eInterface type: Analog\u003c\/li\u003e\n\u003cli\u003ePin Definition:  1-Output  2-GND  3-VCC\u003c\/li\u003e\n\u003cli\u003eHigh sensitivity to Hydrogen (H2)\u003c\/li\u003e\n\u003cli\u003eSmall sensitivity to alcohol, LPG,cooking fumes\u003c\/li\u003e\n\u003cli\u003eStable and long life\u003c\/li\u003e\n\u003cli\u003eSize: 40x20mm(1.57\"x0.79\")\u003c\/li\u003e\n\u003cli\u003ePin Definition: 1-Output 2-VCC 3-GND\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eArduino Hydrogen Gas Sensor (MQ8) x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0133\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67580465578061,"sku":"E34015-001","price":19.64,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E34015-win1.jpg?v=1791320554","url":"https:\/\/www.mlab.com.au\/products\/gravity-analog-hydrogen-gas-sensor-mq8","provider":"MLAB","version":"1.0","type":"link"}
