摘要

本論文係採用盛群微控制器HT66F50的8位元MCU並結合一氧化碳感測器MQ7與風扇在天花板上，將室內一氧化碳的濃度輸入至MCU做計算，當濃度超過100ppm即自動開啟風扇，將一氧化碳抽離室內空間，若濃度超過200ppm則立即發出警示聲。由於市面上販售之一氧化碳偵測器僅發出警示聲，且售價金額偏高，因此本研究將設計以低成本、多功能為方向。
　　本論文與市售產品不同，擁有不斷電系統，不僅在停電的時候可繼續正常運作，還有提供緊急照明與USB充電，因現今人們越來越依賴3C產品，所以在停電的狀況下是非常實用，更重要的是可以一直監控室內一氧化碳濃度，讓我們避免這些意外。

The study adopted a Holteck HT66F50, featured with Flash Memory A/D type 8-bit microcontroller (MCU), and connected with a MQ7 gas sensor and ventilation fans on the ceiling to input the level of carbon monoxide (CO) into the MCU for calculating. As the level of CO in the air reaches 100 ppm, the fans will be activated to exhaust CO out to the space; besides, if the level of CO in the air is over 200 ppm, the buzzer will sound indicating “Alarm”. Carbon monoxide detectors on the market can only buzz during alarm and chirp if a trouble is found, and the prices are high; thus, the study focused on designing a low-cost and multi-functional carbon monoxide detector.
The detector is far different from those on the market due to its uninterruptable power system (UPS) which can continuously run the device during power failure and provide an emergency lighting and be a USB charger. Nowadays, people have relied on 3C products; therefore, the detector has become practical, especially during power failure. The most important feature is that it can monitor the level of carbon dioxide indoor and prevent people from suffering carbon dioxide poisoning.
