| Summary: | 碩士 === 健行科技大學 === 電子工程系碩士班 === 103 === In recent years, disasters such as fire and gas explosion were frequently reported by TV news, the Internet and other media. Most of these disasters were caused by human negligence. If more attention was paid on early signs of these disasters, they are not inevitable. In this paper, we propose a cloud environment monitoring system based on internet MQTT communication protocol. The objective is to monitor the environment, access the environmental information by sensors. If a precursor of a disaster is determined (or a disaster has occurred), the information will be immediately broadcasted via the Internet to the relevant personnel to exclude the disaster. Our study is implemented on Raspberry Pi platform. A variety of environmental sensors transmit information to the Raspberry Pi platform. Based on the MQTT protocol, the values of sensors can be transmitted to the Server for analysis and the result will be broadcasted via the Internet to the end users.
