一種遠端灌溉監控系統之設計

The Design of a Remote Irrigation Monitoring System

遠端監控灌溉系統可以改善辛苦的農作灌溉環境。監控系統以土壤濕度感測器和Wi-Fi無線通訊模組構成感測節點，置於農作物附近，土壤濕度感測傳到一個Wi-Fi中繼節點，然後上傳到無線基地台連上網際網路，網際網路端以Google試算表為人機介面，紀錄和呈現土壤濕度狀況。試算表上可以設定啟動灌溉的濕度值，濕度值下傳到中繼節點控制灌溉系統。系統可以低成本和不用專屬網路伺服器的架構下，幾乎跨平台的由各種電腦或攜帶式設備，進行遠端監測和自動灌溉設定。 The remote irrigation monitor system can improve the laboring irrigation for agriculture. The monitoring system uses a soil moisture sensor and a Wi-Fi wireless communication module to form a sensory node near the crop. The soil moisture sensing is transmitted to a Wi-Fi relay node, and then uploaded to the access point and connected to the Internet. On the Internet, we can use Google Spreadsheet as a human-machine interface to record and present soil moisture conditions. The moisture level at the beginning of irrigation can be set on the Spreadsheet and transmitted to the relay node to control the irrigation system. The system can be used for remote monitoring and automatic irrigation settings on almost cross-platform computers or portable devices under a low-cost and non-exclusive network server architecture.
