Project Matter is a student-led think tank started by students from Renaissance College , Ma On Shan and its current project focuses on installation of real-time self-built sensors in different school campuses across the city.

The data these monitors collect from the schools will provide an unprecedented level of detail about Hong Kong’s air quality in campus environment. Their focus is to present the air quality data to the school authorities through the air monitoring network and it also aims to protect the health of children and students.

Clean Air Network shares the same goal with the student team to enhance the health of children from air pollution. We support the team as part of CAN’s project called “Let Our Children Breathe”.

Students from Project Matter visit Shatin EPD air monitoring station


In early May, with the help of the Environmental Protection Department, we did a site visit together with the students to the Shatin air monitoring station to help them understand the monitoring mechanisms and also to calibrate their self-made sensors.

They are aiming at 5 schools at the moment like Diocesan Boys School, Chinese International School, Sha Tin College in the first phase. More schools will be going to join the monitoring network in the future. The data generated by this network will be available for the public to view on an online map soon.

Eugene, the founder of Project Matter, says “Our school Renaissance College is 8 km away from the Sha Tin air monitoring station and we have to depend on the air quality data of that station to define the air quality in our school campus. Through the air quality monitoring network, we want to bring air monitoring closer to the schools”.

Kindly contact us if your school is interested in this project. We will be happy to see more parents and teachers starting to understand and address the devastating impact of air pollution on children’s health.
