Kaltluftseen.ch, an initiative by Stephan Vogt, monitors frost hollows in Switzerland. In this season he started to use Decentlab's air temperature and relative humidity with radiation shield (LoRaWAN) and the Data Access platform to monitor Hintergräppelen, a promising site to reach lowest temperatures in Switzerland.
On Tuesday morning we recorded a new minimum of this season with -21.89 °C. We are looking forward for a really cold winter.
LoRaWAN network by Swisscom LPN
One full year of soil moisture, electrical conductivity and temperature data sent over public LoRaWAN network from 3 locations in Switzerland.
- Measurement and transmission interval: 10 minutes
- Battery usage: 10%
- LoRaWAN network: The Things Network Switzerland
- Applications: Monitor and Control Irrigation Events in Nursery and Greenhouse Applications and Research
We monitor for WSL, Hydrological Forecasts snow level for monitoring of a catchment with a variant of our Level/Displacement Sensor using an ultrasonic sensor. Beginning of this week we caught first snow fall measurements and now we can observe how it melts down or more layers of snow will add up on the cover over the next weeks and months.
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.

Zeitschrift WOHNEN published a report about LoRaWAN. It gives an introduction to LoRaWAN and highlights several use cases including Carbosense. Illustrations for the report show our devices in action. Read full report
Visit us on 14th June at LoRa Alliance All Members Meeting in 3rd Floor Franklin Institute, Philadelphia. See you there.
Since mid of April Empa, Laboratory for Air Pollution / Environmental Technology, operates our LoRaWAN CO2 sensors next to their Nabel reference site to conduct outdoor calibration. The devices transmit readings over Swisscom LPN, based on LoRaWAN technology. In the next months we will roll out more than 300 CO2 sensors over whole Switzerland.

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.
