Product description: Unit MQ-5 - flammable gas sensor - M5Stack U199
The MQ-5 Unit is a compact combustible gas detection module based on the MQ-5 semiconductor sensor and an integrated STM32G030F6P6 microcontroller. Designed to detect the presence of gases such as LPG, methane, and propane , it is an effective component of security, environmental monitoring, and automation systems. The module communicates with a host device via an I2C interface , providing not only measurement data but also diagnostic information such as reference voltage, sensor voltage, raw ADC values (12-bit and 8-bit), firmware version, and integrated thermistor temperature. This gives the user complete control over the sensor's operation and the ability to precisely analyze data.
