Description
Description Unit MQ is a combustible gas detection unit based on the semiconductor gas sensor (MQ-5), integrated with an MCU (STM32G030F6P6). 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. Features Built-in STM32 core controller I2C communication interface Supports detection of various combustible gases (such as LPG, methane, etc.) Supports two modes: continuous heating and intermittent heating with customizable periods Integrated thermistor for device temperature monitoring Readable internal reference voltage and sensor voltage Standard MQ sensor interface, compatible with multiple sensors (such as MQ-2, MQ-3, MQ-7, MQ-135, etc.) Development Platform: Arduino UiFlow2 Includes 1 x Unit MQ 1 x HY2.0-4P Grove Cable (20cm) Applications Specifications Specification Parameter MCU STM32G030F6P6@32-bit ARM Cortex-M0+ processor Sensor MQ-5 combustible gas sensor Communication Interface I2C @0x11, address configurable Operating Current Off mode: DC [email protected] Continuous heating mode: DC [email protected] Detected Gases LPG, methane Detection Range 300 ~ 10000ppm (methane, propane) Recommended Preheat Time in Continuous Heating Mode 20s Product Size 64.0 x 24.0 x 25.0mm Product Weight 19.3g Package Size 138.0 x 93.0 x 25
