The MQ3 sensor uses a tin dioxide (SnO2) sensing element whose conductivity increases with alcohol gas concentration, providing an analog output you can read and process in MakeCode or Python.\n\nConnects directly to PlanetX-compatible expansion boards such as the Nezha, making it easy to add gas detection to micro:bit projects without complex wiring.\n\nKey Features\n\n\nMQ3 Gas Sensor – Detects alcohol vapour concentration\n\nAnalog Output – Proportional to gas concentration\n\nRJ11 Connector – Plug-and-play with PlanetX expansion boards\n\n3.3 V Operating Voltage – micro:bit compatible\n\nMakeCode & Python – Supported programming environments\n\nSKU – EF05032\n\n\n\nNote: The sensor requires a 3-minute preheat period after powering on before readings are accurate.\n\n\nIdeal For\n\nmicro:bit science and chemistry experiments\nAir quality and gas detection projects\nSTEM education and classroom activities\n\n\nPackage Contents\n\n1× ELECFREAKS PlanetX MQ3 Sensor\n\n\nResources\n\nWiki Documentation\n","vendor":"ElecFreaks","product_type":"physical","in_stock":true,"options":[{"name":"Título","values":["Default Title"]}],"variants":[{"id":918,"title":"Default Title","sku":"EF-EF05032","mpn":"EF05032","price":13.73,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
