科技的轉變與以前不同，IBM執行長認為科技發展每隔15年會有一
次大變革，1965年左右以大型主機為主，而1980年左右則是開始普及個
人電腦，到了1995年左右開始進入了網路的時代。以往都是大型主機或
是工業電腦去做許多控制的操作，近年來的趨勢已經改變，物聯網已經
成為現代科技著重發展的主要趨勢，不論是在大型企業上溫度的控制、
智慧城市所導入的方案，亦或是智慧家居的產品，都是現在熱門的項目。
因此本論文從現在生活中的發想，應用基於Atmel AVR 晶片的Arduino
微控制器（MCU），藉由搭配海芯科技公司（AVIA Semiconductor）開發
的HX711 A/D Converter（Analog to digital converter）為提供重量
控制訊號的類比轉數位的晶片，搭配周邊所需要的功能及連接應用，最
後以顯示螢幕以數字方式顯示。
在本論文中藉由Arduino為主要的控制晶片，目標是經過時間控制及
鬧鈴功能，透過程式的撰寫，藉由重量控制去做運算獲得關閉功能，來完
成壓力感測的應用

The transformation of science and technology is different from before.
The CEO of IBM believes that there will be a major change in the
development of science and technology every 15 years. It was mainly
dominated by mainframes around 1965. And around 1985, it began to
popularize personal computers. By the time of 1995, it began to enter the age
of the Internet. The trend in recent years has changed, and the Internet of
Things has become a major trend in the development of modern technology,
whether it is temperature control in large enterprises, solutions introduced by
smart cities, or products of smart homes. All of items is hot now.
This thesis develops from the current life, by the application of Atmel AVR
chip, the industry fabricates Arduino microcontroller (MCU) which coupled
with HX711 A/D Converter (Analog to digital converter) made by AVAI
Semiconductor to form the main workable frame. In our design, the analog
to-digital chip that provides the weight control signal which is matched with
the functions and connection applications required by the periphery, and
finally displayed on the display screen in digital form.
In this thesis, Arduino is the main control chip, and the goal is to
complete the pressure sensing application through time control and alarm
function, through program writing, and by weight control to obtain the
shutdown function.
