For the 2019 edition of the Climate City Cup, an initiative started by the Computational Social Science lab of ETH Zürich, Octanis Instruments designed and produced 200 portable air-quality logger. The device, which can record PM2.5 values, temperature and humidity along with GPS location data, serves as a tool for citizens to track the change in air quality in their cities.

The device can be synchronised with a cloud platform via USB or Bluetooth. It was designed in "maker-friendly" way, meaning that it can be easily re-configured or expanded with other sensors by tech-savvy users.
