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.

Very Long Range communication with Swissom LPN

Yesterday a new LoRaWAN gateway was brought online by Swisscom LPN near Aarau (Wasserflue). Our node located in Fehraltorf recording precipitation successfully transmits its data over this gateway located more than 56km away!
The node is part of the research project Urban Water Observatory from Eawag, Department Urban Water Management in which the urban water cycle is monitored with spatially distributed sensors to answer pressing questions regarding future developments of water infrastructure.

The node further sends data over LoRaWAN gateway located on top of Bachtel since last Friday. Already before data has been received from the gateways on Zürichberg and Uetliberg.

It is great to see how Swisscom LPN network grows and data reliability and coverage increases.

The Things Network coverage in region of Lake Murten

End of July Thomas Amberg (@tamberg) and Decentlab did some LoRa (The Things Network) range tests in the region of Murten for TTN-Bern. See coverage map below including some measurements recorded crossing the lake by Thomas.

Soil moisture & temperature monitoring using LoRa infrastructure of TheThingsNetwork Zurich

We started a soil monitoring demo for evaluating TheThingsNetwork (LoRa infrastructure) and our rugged GS3 soil moisture & temperature node.

We deployed 3 nodes in different locations in Zurich. Sensor data is transmitted over LoRa to the gateways which are up to 7.5km away from the sensor location.

Thanks to the TheThingsNetwork Zurich for the infrastructure.

Realtime information of the LoRa communication (RSSI, Spreading Factor, Gateways, SNR ...)  of the nodes

Decentlab LoRa sensors now with adaptive data rate (ADR) enabled by default

This strongly improves data transfer times and optimizes the usage of the limited bandwidth in the 868MHz ISM band in which the LoRaWAN gateways operate.

Our nodes periodically adapt spreading factor by instructions sent from the LoRaWAN network server. With this we help the operators to run as much as possible nodes in parallel and let them coordinate the nodes for optimal data rate and range. The nodes significantly benefit by the lower power consumption in higher data rate modes.

With SF7 transmit time is 20 times shorter than with SF12!
