本研究主要是進行無線感測器系統之研究；主要的概念構想是架構一種從環境擷取電源之無線感測器，達成感測器無線佈署之功能。本研究整合太陽能發電模組、電源管理模組、8051 微控制器控制電路模組與ZigBee 無線傳輸模組等模組以進行可行性研究。為了解決電源供電能力限制問題，本研究並設計使用二階段電容的電源管理模組於無線感測器模組架構中，以達到無線感測器系統穩定操作的目的。本文經由硬體實作與信號量測予以測試，其結果有助於驗證所提架構
之可行性以及確立未來發展方向。

The topic of this paper is the feasibility study of energy harvesting wireless sensor system. The experimental wireless sensor is integrated by solar cell charging subsystem, electric power management module, 8051 MCU controller module and ZigBee module. In order to manage the limited harvesting electric power, we implement a dual-capacitor electric power management module to archieve stable system operation. After the preliminary verification and system test, the concept and system design of the wireless sensor system are feasible and the system is very suitable for environmental surveillance applications.
