本論文主要目的在於研究與製作一套智慧農業環境光纖監控系統，此系統包含三大部分，分別是農業生產所需之感測器模組系統、光纖通訊遠距離傳輸系統和即時遠端監控農業生產系統，並設計可同時監控兩個以上農業溫室。為了達到溫室生產環境監控之目的，此溫室系統內架設了各式感測器，透過單芯光纖做雙向通訊，並即時監控遠端的感測器之信號，當偵測出異常信號時將立即反映回饋資訊。
因此，本論文展示智慧農業需要的即時環境監控系統，藉由光纖與各式感測器的整合，提供一個可以促進高生產效率、低建置成本、對異常狀況可快速反應的解決方案。

This thesis presents a fiber-optic monitoring system for intelligent agricultural environments, which is divided into three parts. One is a system of diversified sensors required for smart agriculture, including those for measuring voltage, temperature, humidity, carbon dioxide, pH values and other parameters. The second is a transmission system that uses the technique of optical fiber communication starting with RS485-formatted pick-up signals in greenhouses. And the third is a real-time computer-based display system that shows the agricultural greenhouse conditions.
The single-mode fiber system can monitor multiple agricultural greenhouses and can also avoid the interference arising from the agricultural production environment. Besides, the remote monitoring system using multiple sensors can have a surveillance over the agricultural production environment to get the abnormal conditions that could be remedied by corresponding measures in the shortest time.
This thesis demonstrates the working principle of remotely monitoring an intelligent agricultural environment containing two separate greenhouses with a low construction cost and a rapid surveillance. This could provide a significant solution for agricultural planting in the trend of aging society with fewer children
