It is mainly used for detecting combustible gases (such as propane, methane, etc.) in the environment. This unit communicates with various host devices via the I2C interface and can obtain internal reference voltage, sensor voltage, 12-bit and 8-bit ADC raw values, firmware version, thermistor temperature, and other information. It supports two heating modes to bring the sensor to the optimal operating temperature: continuous heating mode and intermittent heating mode. In continuous heating mode, the sensor heats up faster and responds with data more quickly. In intermittent heating mode, the heating cycle can be flexibly configured to optimize device power consumption. This product is suitable for various safety and monitoring applications such as smart homes, air quality detection, and industrial safety.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0056\/7689\/2250\/files\/1_fbe93be8-d5e6-433a-9da5-ce158e184934.webp?v=1766547601\u0026amp;width=700\" alt=\"Unit MQ\" style=\"width: 80%; height: auto;\"\u003e\u003c\/p\u003e\n\u003ch2 data-id=\"Features\" id=\"features\"\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt-in STM32 core controller\u003c\/li\u003e\n\u003cli\u003eI2C communication interface\u003c\/li\u003e\n\u003cli\u003eSupports detection of various combustible gases (such as LPG, methane, etc.)\u003c\/li\u003e\n\u003cli\u003eSupports two modes: continuous heating and intermittent heating with customizable periods\u003c\/li\u003e\n\u003cli\u003eIntegrated thermistor for device temperature monitoring\u003c\/li\u003e\n\u003cli\u003eReadable internal reference voltage and sensor voltage\u003c\/li\u003e\n\u003cli\u003eStandard MQ sensor interface, compatible with multiple sensors (such as MQ-2, MQ-3, MQ-7, MQ-135, etc.)\u003c\/li\u003e\n\u003cli\u003eDevelopment Platform:\n\u003cul\u003e\n\u003cli\u003eArduino\u003c\/li\u003e\n\u003cli\u003eUiFlow2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Includes\" id=\"includes\"\u003eIncludes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Unit MQ\u003c\/li\u003e\n\u003cli\u003e1 x HY2.0-4P Grove Cable (20cm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-id=\"Applications\" id=\"applications\"\u003eApplications\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0056\/7689\/2250\/files\/6_25d9e39e-7121-4049-8a22-496ff864f4e1.webp?v=1766547617\u0026amp;width=700\" alt=\"Unit MQ\" style=\"width: 80%; height: auto;\"\u003e\u003c\/p\u003e\n\u003ch2 data-id=\"Specifications\" id=\"specifications\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"table-container\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMCU\u003c\/td\u003e\n\u003ctd\u003eSTM32G030F6P6@32-bit ARM Cortex-M0+ processor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor\u003c\/td\u003e\n\u003ctd\u003eMQ-5 combustible gas sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eI2C @0x11, address configurable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Current\u003c\/td\u003e\n\u003ctd\u003eOff mode: DC 5.02V@6.88mA\u003cbr\u003eContinuous heating mode: DC 5.05V@188.89mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetected Gases\u003c\/td\u003e\n\u003ctd\u003eLPG, methane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e300 ~ 10000ppm (methane, propane)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Preheat Time in Continuous Heating Mode\u003c\/td\u003e\n\u003ctd\u003e20s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e64.0 x 24.0 x 25.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e19.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e138.0 x 93.0 x 25.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross Weight\u003c\/td\u003e\n\u003ctd\u003e24.7g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0056\/7689\/2250\/files\/1920x2260_a8ac24b4-44fc-4e1a-84d7-eaf9081b4c30.webp?v=1766547490\u0026amp;width=700\" alt=\"Unit MQ\" style=\"width: 80%; height: auto;\"\u003e\n\u003ch2\u003eLearn and Documents\u003c\/h2\u003e\n → DOCUMENTS \n\u003c\/div\u003e","brand":"m5stack-store","offers":[{"title":"Default Title","offer_id":49566416306403,"sku":"vbq1787247240182","price":3.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/2961\/4819\/files\/m5stack-mq-5-gas-unit-stm32g030_1.webp?v=1787247246","url":"https:\/\/regalcladfashion.shop\/products\/m5stack-mq-5-gas-unit-stm32g030","provider":"My Store","version":"1.0","type":"link"}
