Broadcast combustible gas alarm system design microcontroller-based voice and TTS module

Introduce a combustible gas alarm system based on microprocessor and Iflytek TTS voice module. By detecting combustible gas content in the environment using combustible gas sensor, while detecting ambient temperature and flame by infrared and UV sensor respectively, this system could display or broadcast the current measurement results of combustible gas content, fire forecasts and emergency plan message via the LCD and TTS voice module. The paper presented the detailed system hardware design and software flow chart. The system is simple, stable, convenient operation, fast response, also with the feature of intelligent voice broadcast. It could provide reference for the design and application of similar devices.
