Interface for Easy Integration: Designed with a standard communication interface, the gas sensor unit can be quickly connected to cores, , ESP32, and other development boards, simplifying wiring and reducing development time. Combustible Gas & Air Quality Detection: Supports detection of a variety of combustible gases (such as methane, propane, and LPG), enabling real-time air quality assessment and early-warning functions suitable for smart home, safety monitoring, and industrial DIY applications. DIY Project Development Kit: Perfect for makers, students, and engineers, this unit allows you to easily build custom gas detection systems, IoT monitoring terminals, and environmental data loggers. It is suitable for learning sensor principles and rapid prototyping. Compact Module Design: The compact, module is easy to embed into existing ecosystems and other electronic enclosures. Standard mounting holes and a plug-and-play design help tidy, stable installation. Unit is a combustible gas detection unit based on the semiconductor gas sensor (-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 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 hea 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.
