在目前互聯網與創客興起的時代,容易於使用的組件已經成為重要關鍵因素,本論文研製一個具有雲端資料庫儲存與推播功能的單晶片監測系統,方便沒有專業知識的人員使用。它提供有電壓監測、電壓臨界值監測、電壓準位監測及電壓邊緣監測等四種監測方法。它利用微控制器本身的類比數位電壓轉換、外部觸發與輸入輸出接腳作為監控電壓之核心功能,結合無線網路模組,將電壓數值傳至雲端資料庫做儲存,此外監測電壓達到其觸發條件時送出推播提醒給使用者。此外本論文專為該模組設計一個智慧型手機應用軟體,使用者透過本系統模組之手機應用軟體便可監測電壓歷史記錄以及接收電壓觸發之推播提醒。另外使用者可因個人使用喜好來設定推播提醒的內容、推播提醒間隔時間。
Easy to use the components in the applications of Makers have become an important concern in the Internet of Things age. Providing that easy to use without professional knowledge background for people, this thesis develops a single-chip monitoring component supporting cloud database storage and the function of push notification. It provides four monitoring methods including voltage monitoring, voltage threshold monitoring, voltage level monitoring and voltage edge monitoring. It utilizes the microcontroller's analog-to-digital voltage conversion, external trigger and the input and output pins as the core function for monitoring the supervisory voltages. All those voltage values are transferred to the cloud database for storage by Wi-Fi module. In addition, when the monitoring voltage reaches its trigger condition, it sends out the push notification to the user. Moreover, we design an App for the user to change the content of the push notification if need, and the time interval of pushing notification. Besides, users can view the values of all records from the mobile application at any time.
