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.
Uniqueness and competitive advantages:
- Indoor or outdoor; day or night
- 90% accuracy
- Simple and convenient to use
