介紹了一種基于氣體傳感器陣列的室內空氣品質監(jiān)控系統(tǒng)。該系統(tǒng)應用半導體氣體傳感器陣列,可以對室內主要的有害氣體得到連續(xù)的響應輸出,輸出信號由微處理器根據(jù)一定算法處理后,得到一個連續(xù)、可比較、可標定的室內空氣品質綜合指數(shù),并可以對綜合指數(shù)或某一有害氣體的超標做出反應,控制換氣扇等外部設備改善室內空氣狀況,聲光報警提醒室內人員注意采取相應措施等。該系統(tǒng)能實時有效地監(jiān)控室內空氣品質,有利于提高生活質量和改善健康狀況。
關鍵詞: 氣體傳感器陣列; 室內空氣品質; 綜合指數(shù); 監(jiān)控
Abstract : An indoor air quality detect and control system based on gas sensor array is introduced. With the sen2 sor array formed by GGS1000/ 2000/ 3000 ,the system can monitor the overall indexing of indoor air quality ,tem2 perature ,and humidity ,determine the condition and send control command to the ventilation fan ,air conditioner and air cleaner. The system is proved to be a simple ,cost2effective and highly2efficient device to evaluate the in2
door air quality in real time and contribute to improvement of living condition.
Key words : gas sensor array ; indoor air quality ; overall indexing ; detect and control
