Overview of the project

The project Carbosense establishes a uniquely dense CO2 sensor network across Switzerland to provide near-real time information on man-made emissions and CO2 uptake by the biosphere. It is formed by three classes of sensors: (i) seven high-precision laser spectrometers (Picarro G1301/G2302/G2401, CRDS), (ii) 20 temperature stabilized, mains powered NDIR low-cost instruments with active sampling and reference gas supply (SenseAir HPP) and (iii) 250 nodes of battery-powered CO2 low-cost diffusive NDIR sensors (SenseAir LP8). The Carbosense network has a spatial focus on the City of Zurich where more than 50 sensors are deployed. Network operations started in July 2017. The sensor nodes use Swisscom's Low Power Network (LPN) for data transmission.

Members

The project is led by the Swiss Federal Laboratories for Materials Science and Technology (Empa) and involves the partners Swisscom, Decentlab and the Swiss Data Science Center (SDSC). External collaborators also contribute to the deployment of the network.
