Using IoT to do away with stuffy air

A great report from Swisscom about our Indoor Ambiance Monitor including CO₂, TVOC and Motion Sensor for LoRaWAN™ and its use for smart building, office comfort, energy efficency and sustainability. It can measure CO2, TVOC, temperature, humidity, motion, presence, illumination and barometric pressure in any room.

Showcasing Indoor Ambiance Monitor at Swisscom IoT Day 2019

Looking back to a great Swisscom IoT Day 2019! A great ambiance and a lot of inspiring talks and discussions. It was a great opportunity to showcase our newly released Indoor Ambiance Monitor with #LoRaWAN measuring all relevant parameters for indoor and building automation

Results of AIRLAB for our awarded Indoor Ambiance Monitor

Results of @AIRLAB_Airparif Challenge for our Indoor Ambiance Monitor with CO2, TVOC, Motion/Activity, Hum, Temp, Air Pressure, Illuminance communicating over LoRaWAN. And we continuously work on it to improve! Full report at …

Airlab Airparif awards two devices for their performance in indoor air quality

We have been awarded by @AIRLAB_Airparif @Airparif for our Indoor Ambiance Monitor capturing CO2, TVOC, Illuminance, Motion, Temperature, Humidity, and Barometric Pressure and sends data over LoRaWAN in the category "Sensibilation sur la qualité de l'air intérieur".

Heavy rain event and flood of River Chriesbach

Last Friday, 08-Jun-2018, we recorded a heavy rain event in Dübendorf. In parallel, precipitation and the level of the River Chriesbach were recorded. In only half an hour an amount of 30 millimeter rainfall has been recorded. Nearby river levels raised by1 meter in only 1.5 hours and flooded the walkways!

All measurements realized with our rain gauge and ultrasonic level meter sending data over LoRaWAN to our cloud infrastructure. Precipitation data provided by Eawag (absolute rain depths are still subject to verification).

Report about Decentlab in Einstein on Swiss Television SRF

On 24th May Decentlab was featured in Einstein on SRF1. Two relevant projects in research, Carbosense/, initiated by Empa, Swisscom and Decentlab and the Urban Water Observatory of Eawag and ETHZ were presented. We are in both projects the main partner for the LoRaWAN based instruments and data services.

The whole program Einstein of that day was dedicated to Internet of Things with a special focus on LoRaWAN.

Newspaper article about Decentlab

Today the newspaper Freiburger Nachrichten published article about Decentlab and its history. Read full article 

So far -33.19 °C is the lowest temperature in 2018 at Hintergräppelen, an initiative by Stephan Vogt, measured in the night of 13th February at Hintergräppelen -33.19 °C with our temperature and humdity sensor with LoRaWAN data transmission. We are looking forward to even lower temperatures!

First snow fall in this season measured at Holzegg


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.

Realtime data of our sensor at the site

Frost hollow monitoring with our air temperature and humidity LoRaWAN sensors, 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.
