當前台灣面臨人口結構老化問題，許多老人可能因行動不便或罹患健忘症，即使在家中也容易發生危險。而且台灣的居家看護人數亦嚴重不足，倘若能透過科技輔助來協助解決居家老人照護的問題，相信可以讓許多人因此受惠。
近年來隨著物聯網技術的興起，各種感測器與無線通訊技術的整合開發，使用科技輔助來解決上述問題已成為一重要趨勢。因此本論文針對居家老人照護的範疇深入研究，透過感測裝置與智能系統的防護機制，達到居家老人照護的目的。
本論文旨在建立一套瓦斯漏氣和下雨自動監測與安全防護系統。透過瓦斯感測器檢測瓦斯氣體，並自動關閉瓦斯開關和開啟窗戶保持空氣流通，避免氣爆意外發生。雨滴感測器偵測到屋外下雨即自動關閉窗戶，避免雨水淋進屋內讓老人滑倒受傷。

At present, Taiwan faces the problem of aging population. Elders may be at risk even at home because of dementia or impractical to move. Moreover, the number of home care workers in Taiwan is also seriously inadequate. If we can solve the problem of home care for the elderly through technology, I believe many people can benefit from it.
In recent years, with the rise of Internet of Things technology, the integrated development of sensors and wireless communication technologies, using technology to solve the above problems is no longer a problem. Therefore, this paper studies the scope of home care for the elderly, and takes care of the elderly through the protection mechanism of the sensing device and the intelligent system.
The main purpose of this paper is to establish a gas leak and rain automatic monitoring and safety protection system. When the gas sensor detects the gas and automatically closes the gas switch and opens the window to keep the air flowing, avoid accidents. And when the rain sensor detects that it is raining, it automatically closes the window to prevent the rain from drenching the ground and causing the old man to slipped and injured.
