Powering Hong Kong's Smart City with IoT Lampposts
  • Sector:Ambient and Communities
  • Location:Kowloon, Hong Kong
  • Sapiens NAS provides real-time data on critical urban air pollutants, empowering city planners and environmental authorities to gain insights into the area's air quality. By leveraging this data-driven intelligence, the project team plans to use data from this network to make more informed decisions to enhance sustainability and liveability in different districts, supporting Hong Kong's broader smart city transformation. And it has paved the way for wider adoption of NAS sensors in similar smart city technologies across the region. In a smart city prove-of-concept (PoC) project, Sapiens as

    Tethered Balloon Deployment of Sapiens Air Sensors for Planetary Boundary Layer Research at High Altitude
  • Sector:Ambient and community
  • Location:Shanghai, China
  • New particle formation (NPF) is a significant source of atmospheric aerosols, playing a crucial role in influencing global climate. The nucleation and subsequent growth processes involved in NPF have sparked considerable research interest. To advance the study of NPF in China, researchers employed the high-performance MAS series to measure air quality at elevations exceeding 1000 meters. This investigation focused on the vertical profiles of key pollutants and their formation mechanisms, providing valuable insights into atmospheric dynamics.

    Ultra Air Monitoring Network for Dense Population
  • Sector:Ambient and community
  • Location:Macau, China
  • ​To address Macau's complex and highly variable air pollution patterns, seven strategically positioned Sapiens MAS-AF300 systems form a comprehensive monitoring network across the region. This deployment empowers Macau Meteorological and Geophysical Bureau of Macau Government with hyperlocal, real-time data – transforming the challenge of heterogeneous pollution distribution into actionable insights for evidence-based decision-making.

    Ambient Air Quality Monitoring in Macao
  • Sector:Ambient and Communities
  • Location:Macau, China
  • This project is commissioned by the Macao Meteorological and Geophysical Bureau. It adopts Sapiens’ MAS solution to conduct long-term near reference monitoring of Macao’s major pollutant categories, capture the spatial distribution of key pollutant (PM₂.₅, PM₁₀, NO₂, O₃, CO, SO₂) concentrations, as well as meteorological data including ambient temperature, humidity, wind speed, wind direction and atmospheric parameters, so as to realize dynamic monitoring of the temporal and spatial variations of major pollutants.
