Participants of the "Ultraviolet Radiation Measurement and Application Design Competition" all gathered at the Project Exhibition, Judging and Award Presentation Ceremony held on April 29, 2018 (Sunday) at the Library Extension (New Wing) of The University of Hong Kong. The competition was jointly organized by the Faculty of Engineering of HKU, the Hong Kong Observatory (HKO) and the Hong Kong Meteorological Society (HKMetSoc).
This competition is a major event of "The invisible ultra-violet (UV) radiation" project funded by the HKU Knowledge Exchange Fund. The project is led by Professor Francis C.M. Lau from the Department of Computer Science, with Dr. Beta C.L. Yip and Dr. Ivy K.Y. Wong as core members.
45 teams of students from primary and secondary schools in Hong Kong showcased their own designs of UV radiation measurement devices at the exhibition to compete for a number of awards. They make good use of UV radiation for sterilisation, sun screen evaluation, curtain control and catching mosquitoes. Participants gather and share their ideas, demonstrate their work, and exchange their knowledge with each other.
The UV measurement devices range from simple handmade ones from materials UV beans, plastic, wood, paper boxes and buzzers, to sophisticated systems with UV sensors, motion sensors, accelerometers, credit-card sized computers, 3D-printed models and laser-cut plastic sheets.
Dr. Beta C.L. Yip, a judge of the primary school category, was delighted that participants were enthusiastic in demonstrating their UV measurement devices and innovative applications not only to the judges, but also to members of other competing groups. They exchanged ideas and appreciated the works of each other.
Professor Francis C. M. Lau, the Principal Investigator of the project, is very much impressed by the hard work of the students shown in the competition.
