The sensor can measure concentrations of flammable gas of 300 to 10,000 ppm.The sensor can operate at temperatures from -20 to 50\u00b0C and consumes less than 150 mA at 5 V. Please read the MQ2 datasheet (184k pdf) for more information about the sensor. Connections Connecting five volts across the heating (H) pins keeps the sensor hot enough to function correctly. Connecting five volts at either the A or B pins causes the sensor to emit an analog voltage on the other pins. A resistive load between the output pins and ground sets the sensitivity of the detector. Please note that the picture in the datasheet for the top configuration is wrong. Both configurations have the same pinout consistent with the bottom configuration.The resistive load should be calibrated for your particular application using the equations in the datasheet, but a good starting value for the resistor is 20 kO. We offer two breakout boards that make it easier to interface with these sensors: a Pololu carrier board and a SparkFun carrier board. The Pololu version is shown below.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ALLNET 4duino Two colour LED\/ zweifarbige LED<\/p>\n","protected":false},"featured_media":114676,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[1329],"product_cat":[2549,2547,66,234,28],"product_tag":[],"class_list":["post-61646","product","type-product","status-publish","has-post-thumbnail","product_brand-allnet","product_cat-4duino-einplatinencomputer-entwicklung","product_cat-einplatinencomputer-entwicklung","product_cat-maker-werkstatt","product_cat-sensoren-aktoren-displays","product_cat-smart-home-gebaeudetechnik","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>ALLNET 4duino Two colour LED\/ zweifarbige LED - INOSHOP<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/inoshop.at\/index.php\/produkt\/allnet-4duino-two-colour-led-zweifarbige-led-61646\/\" \/>\n<meta property=\"og:locale\" content=\"de_DE\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"ALLNET 4duino Two colour LED\/ zweifarbige LED - INOSHOP\" \/>\n<meta property=\"og:description\" content=\"ALLNET 4duino Two colour LED\/ zweifarbige LED\" \/>\n<meta property=\"og:url\" content=\"https:\/\/inoshop.at\/index.php\/produkt\/allnet-4duino-two-colour-led-zweifarbige-led-61646\/\" \/>\n<meta property=\"og:site_name\" content=\"INOSHOP\" \/>\n<meta property=\"article:modified_time\" content=\"2026-10-23T22:03:12+00:00\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Gesch\u00e4tzte Lesezeit\" \/>\n\t<meta name=\"twitter:data1\" content=\"1\u00a0Minute\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/\",\"url\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/\",\"name\":\"ALLNET 4duino Two colour LED\\\/ zweifarbige LED - INOSHOP\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/inoshop.at\\\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/#primaryimage\"},\"image\":{\"@id\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/inoshop.at\\\/wp-content\\\/uploads\\\/2026\\\/10\\\/inoshop-61646.jpg\",\"datePublished\":\"2026-10-09T12:40:20+00:00\",\"dateModified\":\"2026-10-23T22:03:12+00:00\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/#breadcrumb\"},\"inLanguage\":\"de\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"de\",\"@id\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/#primaryimage\",\"url\":\"https:\\\/\\\/inoshop.at\\\/wp-content\\\/uploads\\\/2026\\\/10\\\/inoshop-61646.jpg\",\"contentUrl\":\"https:\\\/\\\/inoshop.at\\\/wp-content\\\/uploads\\\/2026\\\/10\\\/inoshop-61646.jpg\",\"width\":1748,\"height\":1299,\"caption\":\"ALLNET 4duino Two colour LED\\\/ zweifarbige LED\"},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/produkt\\\/allnet-4duino-two-colour-led-zweifarbige-led-61646\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Start\",\"item\":\"https:\\\/\\\/inoshop.at\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Shop\",\"item\":\"https:\\\/\\\/inoshop.at\\\/index.php\\\/shop\\\/\"},{\"@type\":\"ListItem\",\"position\":3,\"name\":\"ALLNET 4duino Two colour LED\\\/ zweifarbige LED\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/inoshop.at\\\/#website\",\"url\":\"https:\\\/\\\/inoshop.at\\\/\",\"name\":\"INOSHOP\",\"description\":\"IT-Hardware &amp;
