空氣品質為近年來臺灣非常重視的課題，環保署雖有超過20年的長期監測，然因測站空間密度不足，致使參考性備受大眾質疑。近年來許多社團及學者藉由物聯網技術的成熟，推動自行觀測，輔助瞭解生活周遭的空氣品質時空變動，已有非常傑出的成果。本研究考量山區高濕環境，自製簡易空氣品質觀測系統，並以環保署竹山站進行比對驗證。結果顯示，本系統可穩定輸出具參考性的數據，檢驗兩個平價(細)懸浮粒子感測器之一的型號: PMS3003資料，經水氣修正後PM₂․₅及PM₁₀的R²分別可達0.78及0.67，較適合做為山區空氣品質輔助監測使用。

Recently, air quality is an important issue in Taiwan. The Environmental Protection Administrator (EPA) has been monitoring air quality for more than 20 years. The validity of results from a few of the observed stations are still questioned by the public. In recent years, aided by the maturity of Internet of Things (IoTs) technology, many associations and researchers have been promoting self-observation to help understand the temporal and spatial patterns of air quality in Taiwan, and have produced outstanding results. In this study, we considered the high-humidity environment in the montane areas and designed a simple air quality observation system, in which two (fine) particulate matter sensors were verified by the EPA Zhushan Station. The results showed that the system can consistently output reliable data. Moreover, comparing with the model PMS3003 sensor and the EPA standard instrument, the R2 values of the monitored PM 2.5 and PM measurements can reach 0.78 and 0.67, respectively, after being adjusted with 10 consideration of water vapor. Therefore, this model is suitable for use in montane areas as a complementary air quality observation system.
