By simply taking a photo using a mobile phone, PhotoAir can measure PM2.5 concentrations indoor or outdoor, day or night in real time regardless of weather conditions. These functions are achieved through the development of advanced computer vision and artificial intelligence algorithms in the light of physical optics to extract complex features embedded in the photo accounting for different illumination attenuations. With real-time alerts on pollution levels and forecasting tools, users can then keep track of their exposure to PM2.5 to make informed travel plans by avoiding heavily polluted areas.

• Indoor or outdoor; day or night

• Real-time

• 90% accuracy

• Simple and convenient to use

​

不論日夜和各種天氣狀況，只要擁有一部配備攝影功能的智能手機，即可透過PhotoAir軟件輕鬆獲得即時室內外PM2.5細懸浮微粒濃度資訊。受惠於電腦視覺及人工智能算法的發展，先進科技讓軟件可在不同光度的照片中以物理光學進行分析，從而獲取複雜的數據。根據軟件內的即時空氣污染警報和預測工具，用戶可紀錄他們曝露於PM2.5細懸浮微粒的時間並提前計劃行程，避開高污染地區。

• 室內、室外；日間、晚間

• 即時

• 90%準確度
