摘要
本系统以MB95F204K单片机为核心,利用传感器对O_2、CH_4、CO、H_2S多种气体浓度进行精确检测以及温度、湿度环境测量的硬件电路设计和软件实现;同时选用了键盘、液晶显示实现人机交互,带语音报警功能。系统各模块之间综合应用了I^2C、SPI总线通信技术;气体信号采集根据气体成分不同选用了不同的传感器,提高了系统的测量精度和抗干扰能力。
The core of system is MB95F204K SCM. Hardware circuit design and software implementation of using sensors can accurately detect gas concentrations of O2, CH4, CO and H2S, as well as temperature and humidity measurement; Also use the keyboard and LCD display to achieve human-computer interaction, with a voice alarm. System mod- ules integrated apply Bus Communication technology of 12C, SPI; According to different gas composition, gases signal acquisition select different sensors, improving the system's measurement accuracy and Anti-jamming capability.
