We can all be amateur meteorologists right here at Science Park.

 

The Sensor Hub at Science Park has a series of sensors and IoT tools that monitor the ambient and environmental conditions around us. They deliver real-time measurements, with data available for further analysis.

 

With the sensors at the Park, you can gauge the level of PM2.5, lightning activity nearby, or even water quality parameters. 

 

Objectives of the Sensor Hub

  • To provide laboratory services and a testbed for pilots and trials of new sensor devices/systems at Hong Kong Science Park
  • To transform new sensing concepts into real-life applications
  • To promote the adoption of new sensor technologies for smart city
  • To accelerate the development of new integrated sensor systems and commercialisation

Key Functions of the Sensor Hub

  • Test smart sensors in a heterogeneous living environment
  • Acquisition of user data and feedback on smart sensors
  • Evaluation of the key building blocks of smart sensor systems for extending sensors into new markets and new applications
