本研究為此設計與實作多媒體感測節點、環境感測節點、嵌入式無線閘道器以及後端管理系統。我們將VS1053音樂模組及多種環境感測器整合至Octopus II無線感測平台，並透過特定的通訊序列介面將其連結，實作出多媒體感測節點，其可以感測到周圍民眾的活動，也可以播放預存之多媒體音樂來和民眾互動，亦可播放線上串流音樂，另外我們整合WiFi模組、藍芽模組以及Octopus II無線感測平台至Arduino嵌入式微控制板，實作出嵌入式無線閘道器，透過其可橋接網際網路、802.15.4網路和藍芽網路，最後我們開發後端系統管理系統，維護者可以透過其監控多媒體感測節點是否異常，以及線上更新多媒體感測節點之音樂檔案。
Wireless Sensor Networks(WSNs) have been widely applied in many applications, including environmental monitoring, smart life, habitat monitoring and tracking as well as healthy monitoring. However, few art applications are developed by applying the technologies of WSNs. This thesis proposes a platform, called WSN Sound-Tree Sidewalk (S-TS) System, which integrates art design and new technologies such as sensing, wireless communication, cyber physical system and embedded system designs, aiming at providing an interactive and artistic production. The proposed platform mainly consists of a number of mushrooms, which are able to interact with people through multi-track music playing. In the developed S-TS system, the music mushrooms play the major role. Each music mushroom supports a variety of functions, including sensing, communication as well as music playing. Inside each music mushroom, several sensing components, including temperature, humidity, motion and microwave sensors, are connected to the Octopus II for collecting environmental information and motion detection. Based on the collected information, the Octopus-II makes decision for the music selection and then sends command to the connected VS1053 chip which stores the multi-track music and is able to play the designated music. A gateway s that integrates several heterogenous wireless interface, including Bluetooth, Zigbee, as well as WiFi is designed and implemented in this thesis to enable the communication between the mushrooms, android mobile phone and the access point. In addition to play the stored music, the designed S-TS system is able to receive the music from Internet through the developed Gateway and then play the music in a streaming manner. We expect that the proposed WSN Sound-Tree Sidewalk can provide people with an interactive, artistic, smart, and creative landscape.
