The launch took place at the University of Rwanda's College of Science and Technology (CST-UR) on Friday, October 10, 2025.
Using Internet of Things (IoT) technology, the devices, designed to be mounted on both motor vehicles and motorcycles, continuously gather and transmit air quality data in real time. They monitor key indicators such as temperature, humidity, particulate matter (PM2.5 and PM10), and gases including ozone (O₃), nitrogen dioxide (NO₂), carbon dioxide (CO₂), and sulfur dioxide (SO₂).
Data will be analysed in real time, enabling city administrators and researchers to identify high-risk pollution areas and take early preventive action.
Representing the university, Professor Richard Musabe said the initiative will be highly beneficial to Kigali and its surrounding areas.
Dr. Eric Nizeyimana, the researcher behind the project, explained that the idea began in 2020 as a response to rising global air pollution. The research was conducted at the African Centre of Excellence in Internet of Things (ACEIoT).
'Air pollution is a major challenge in Kigali and beyond. It is crucial to develop sustainable solutions to protect both current and future generations,' Dr. Nizeyimana said. The project will initially focus on Kigali, with plans to expand to other provinces.
Eddah Barasa, Research Grants Officer at the Regional Scholarship and Innovation Fund (RSIF) under PASET, praised the initiative for its innovative use of technology and potential impact. RSIF/PASET also financially supported the research.
The Clean City IoT Device project not only collects and analyses real-time air quality data to guide preventive measures but also aims to raise public awareness, foster scientific collaboration, and engage communities in protecting urban environments.
Key partners in the project include the Rwanda Environment Management Authority (REMA), Meteo Rwanda, the National Council for Science and Technology (NCST), Rwanda Information Society Authority (RISA), and RSIF/PASET.
