EmpaQuarterly Report: CO2 under surveillance

This new dense, globally unique sensor network records spatial and temporal changes in CO 2 levels in the atmosphere as well as humidity and temperature. All data are accessible from a web platform. © Empa

The distribution of the CO2 concentration in the City of Zurich averaged over 2013 and 2014. Thanks to the readings from the sensor network, this kind of model calculation will be more precise in future. © Empa

Switzerland is to gain a dense, globally unique CO2 measuring network: 300 sensors permanently collect up-to-date readings, which form the basis for atmospheric dispersion models that are being developed at Empa.

Real time level monitoring demo with our new partner OrbiWise

Check out our new demo together with OrbiWise. OrbiWise provides a full network software solution for LoRaWAN-based networks. Our sensors and application server fits perfectly in combination with the network server from our partner. The demo shows a piezoresistive pressure and temperature sensor for level metering applications like water supply, waste water, ground water or surface water.

See our LoRaWAN sensors live at E-World in Essen

IVU Softwareentwicklung GmbH, our LoRaWAN network partner in Germany, will present our devices and web services at E-World Essen from 6th to 9th February. Visit them at their booth.

The focus of E-world energy & water is innovative solutions for the energy supply of the future - from generation, through distribution and storage to retail, efficiency and green technologies.In the area of storage, decentralised facilities and energy services, the trade fair is growing constantly.Numerous exhibitors present themselves at Germany’s largest Smart Energy trade fair with its focus on renewable energy and intelligent technologies.

We are sponsoring Make Zurich

We are sponsoring Make Zurich 2017

Make Zurich is the civic tech and LoRaWAN hackathon for a better city. It will take place from February 3-4.

It will bring together the local hacker/maker community and the city administration to explore new ways of solving the problems of cities with the help of open networks and civic tech.

There will be six real needs of different departments of the City of Zurich that could be solved with LoRaWAN and civic tech.

Waste water level monitoring

Since mid May Eawag, Department Urban Water Management, is testing our ultra sonic level sensor nodes to monitor waste water reservoirs within  their field site Urban Water Observatory. A spatially distributed monitoring of the urban water cycle will be implemented during the next five years.

The nodes communicate using novel LoRaWAN technology. LoRa communication is an excellent candidate to realize such distributed monitoring applications. With its long range capabilities and low power characteristics it is ideal for the current monitoring setup.

Sensor data from our nodes are sent from below ground, inside sewer manholes and retention tanks to a LoRa gateway located on a roof of a public building. Gateway and network server infrastructure is operated by Loriot.io.

Visualization of sensor data, data export and data access run on our cloud infrastructure. We are looking forward to see first results from the field tests in the near future.
