空氣品質偵測系統設計

Design of Air Quality Detection System

現今人們會將氣象預報中懸浮微粒PM2.5等級，作為是否外出以及佩戴口罩的參考指標，本研究使用物聯網開發板結合粉塵濃度感測器及溫濕度感測器，建置一個簡易的空氣品質偵測系統，並在行動裝置上開發一專屬APP，讓對於注重空氣品質的使用者可以隨時隨時地查詢特定地點的空氣品質數值(PM2.5)及溫度、濕度值。對於注重空氣品質的民眾，在生活中也可以即時知道周圍的空氣品質，當得知空氣品質不良的時候，避免從事戶外活動，如此一來就不會讓懸浮微粒有機會跑進身體而影響健康。

Nowadays, people will use the PM2.5 level of particulate matter in the weather forecast as a reference index for whether to go out and wear a mask. In this study, we use an IoT development board combined with a dust concentration sensor and a temperature/humidity sensor to build a air quality detection system. Beside, we develop an APP on the mobile device, so that users who are sensitive to air quality can check the air quality value (PM2.5) and temperature/humidity values of specific locations at anytime and anywhere. For people who pay attention to air quality, they can also know the air quality around them in real time in their lives. When they know that the air quality is poor, they should avoid engaging in outdoor activities, so that particulate matter will not have the opportunity to run into the body and affect their health.
