OAQ-1-2
Air Quality Sensor
A portable air-quality logging device measuring PM2.5, temperature and humidity.
A portable, battery‑powered device for logging indoor and outdoor air quality.
A portable, battery‑powered device for logging indoor and outdoor air quality.
For the 2019 edition of the Climate City Cup – an initiative of the Computational Social Science Lab at ETH Zürich – Octanis Instruments designed and produced 200 portable air‑quality loggers. The devices measure fine particulate matter (PM2.5), temperature and humidity and, in some versions, GPS position. They are used by citizens and researchers to track how air quality changes over time in their city.
The Air Quality Sensor stores measurements locally and can be synchronised with a web-based dashboard via USB. The hardware and firmware are designed in a maker-friendly way, so tech-savvy users can re-configure the device or extend it with additional sensors for custom experiments.
The device is highly repairable and the battery can be replaced.
