臺灣博碩士論文加值系統

本論文研發一套新型的自動化環境感測監控系統，從古至今人類漫無止境地追求著理想的生活條件，而舒適的環境即為其中重要的一項因素。隨著科技快速的進步卻也造成全球暖化氣候異變，同時居家環境中可能接觸到的危險因子也隨之增加，因此研發一套系統使用多種感測器並結合手機APP來執行智慧化的應用，藉由此套系統來提高居家環境的舒適性、安全性及便利性。
本系統使用盛群HT66F70A微控制晶片做為核心，搭配溫溼度感測器、光強度感測器、粉塵傳感器及多種氣體感測器，將這些環境感測數值透過晶片進行資料運算、存取資料並顯示於LCM顯示器上，同時利用Wi-Fi將數值上傳至手機APP與雲端資料庫做紀錄，此外，晶片還結合溫濕度調節器、電燈、排風扇及警報器等應用做為相對應的處理措施，手機APP隨時顯示當前的各種數值並且可以依照使用者生活習慣不同設定環境中的溫度、濕度、照度基準值，當危險氣體數值過高時，也將透過推播通知讓使用者即時得知住家環境狀況，以此來提升使用者居家環境品質。

In this paper, a new automatic environmental surveillance system was developed, as people have continuously pursued the ideal living condition, where a comfortable environment is one of the important factors. With technological advancement, there is the issue of global warming and abnormality in weather, in which people may come in contact with more risk factors within household environment. Therefore, a system of multiple sensors with mobile APP can improve the comfort, the safety and the convenience of household environment.
The system uses Holtek HT66F70A micro-controller chip as the core, along with temperature and humidity sensor, light intensity sensor, dust sensor and various gas sensors, where the measurements are fed into the chipset for data computation, storage and display on LCM. Meanwhile, via Wi-Fi, the data are uploaded to mobile APP and cloud-based database for record. In addition, the chipset is combined with several applications for temperature & humidity adjustor, light, ventilation fan and alarm as corresponding measures. The mobile APP will continuously display all values and the user can set temperature, humidity and lighting thresholds based on his or her own life habit. When the level of dangerous gas exceeds the norm, push message will inform the user of the household condition, in order to improve the quality of living.
