Semiconductor Gas Sensor Combustible Gas Unit MQ I2C Interface Air Quality Detection Module for DIY Development Kit

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.
