本論文主要目的是建立物聯網環境下之室內環境安全系統，此系統能遠端地監控環境中的溫度以及對人體有害之氣體濃度。如果檢測值超標，系統判定目前的環境會對人體造成危險時，系統會自動地依據使用者目前的所在位置，規劃出最近的避難路線，並呈現在使用者的行動裝置上。由於行動裝置上的GPS定位功能，無法應用在室內定位上，所以本文使用了iBeacon這項技術來實現室內定位。在環境監控模組的部分整合了溫度感測器，以及不同的氣體感測器的感測電路與通訊介面，並利用物聯網的概念，來將感測器所偵測到的數據透過Wi-Fi無線網路，上傳至雲端伺服器上的SQLite資料庫中。除此之外，本文設計了一套Android APP，它能接收來自雲端伺服器的資訊，並且能將使用者目前的所在位置顯示在行動裝置上。

In this thesis, an indoor environment security system is established under the environment of the internet of things, which can remotely monitor the temperature and the gas concentration harmful to the human body in the environment. If the detection value is exceeded, the system determines that the current environment poses a risk to the human body and automatically plans the nearest evacuation route based on the user's current location and presents it on the user's mobile device. Because the GPS positioning function on the mobile device cannot be used in the indoor positioning, this thesis uses iBeacon technology to achieve indoor positioning. The part of environmental monitoring module is integrated the sensing circuit and the communication interface for the temperature sensor and different gas sensors, and is used the concept of internet of things to transmit data of sensor measured through the Wi-Fi wireless network to the SQLite database on the cloud server. In addition, this article designed a set of Android APP, which can receive information from the cloud server, and can show the user's current location on the mobile device.
