由於物聯網相關技術的發展，物聯網相關的服務與應用開始融入人們的生活環境中，而靠者物聯網感測裝置，使用者可以得知環境內的資訊並進而對環境內的物品進行操作。而多虧了開放硬體的進步，使用者可以低成本的建構出自己的物聯網感測裝置並佈置於周遭的環境中。但這些物聯網感測裝置往往都是使用電池供電，故須要有方法將裝置的能量消耗降低來延長裝置壽命，且這些裝置若沒有設計好資料傳送及管理的方法，使用者很難有效地得知環境的資訊。因此本論文設計並實作了使用睡眠計畫及資料壓縮等方法來降低物聯網感測裝置的能量消耗，並設計了一套可以有效地傳輸資料及管理裝置的系統。本論文所提出的系統可以搭配本實驗室所推出的物聯網線上管理平台，於網站上進行管理及控制這些裝置，並且可以在網站上即時看到最新的環境資訊。

Due to the advance of Internet of Things (IoT), the service and application related to IoT has been integrated into people's living space, and the users can know the information about the surrounding environment. Thanks to the progress of open hardware, users can build their own low-cost IoT sensing devices and deploy them in the user’s living environment. However, these devices are usually equipped with battery power, and it is necessary to reduce the energy consumption of the device to extend its lifetime. Without efficient data transmission and management methods on these devices, users are hard to acquire environmental information. Therefore, in this thesis, we design and implement IoT sensing devices that support sleep scheduling and data compression to reduce energy consumption, and design a system that can effectively transmit the data and manage the device. The designed components are integrated into an IoT management platform developed by our lab such that users can manage and control devices on the web, and see the latest environmental information immediately.
