A Proof of Concept project with IBM, Arrow and Mjølner

Carlsberg’s challenge was to find out if they could optimize their operations processes, reduce loss, and make a cost-effective case via an Internet of Things (IoT) platform.

IBM, Arrow, and Mjølner Informatics teamed up in order to create a Proof of Concept (PoC) that would enlighten the benefits and possibilities of an IoT platform for Carlsberg. Amongst several ideas was an IoT set-up to ensure that beer temperatures in Parken Arena are kept at an optimum level.

Carlsberg’s challenge was to find out if they could optimize their operations processes, reduce loss, and make a cost-effective case via an Internet of Things (IoT) platform.

IBMArrow, and Mjølner Informatics teamed up in order to create a Proof of Concept (PoC) that would enlighten the benefits and possibilities of an IoT platform for Carlsberg.


In order to inspect Carlsberg’s equipment and to be able to put forward a line of PoC project suggestions, the team of IBM, Arrow, and Mjølner visited Carlsberg’s beer terminal in Taastrup, Denmark.

Following, the team had an idea session in which it came up with multiple project ideas that were realistic for Carlsberg to implement, as well as cost-effective.

If beer by accident is stored with too high temperatures (cooler breakdown or other equipment failures), product quality can be affected. As a consequence, the beer must, under most circumstances, be discarded.

More specifically, one of the ideas was the IoT project of measuring and monitoring the beer temperatures in the large tanks at the venue/stadium, Telia Parken, in Copenhagen.

For Carlsberg, the project was a good business case because constantly monitoring the temperature of their beer, reduces the risk of the beer going bad. In fact, if Carlsberg accidentally stores the beer at too high temperatures for a small amount of time, it goes bad and they have to throw it out. An unnecessary waste, if Carlsberg utilizes an IoT platform to prevent it.

Measuring and monitoring the beer temperatures is good business.

‘Proof of Concept’

The team and Carlsberg now had a specific project to turn into a pure technical Proof of Concept (PoC).

Mjølner’s team of three developers worked on the project from their offices in Aarhus while continuously coordinating with Arrow. Mjølner set up the framework for the hardware that Arrow developed. IBM delivered the platform Bluemix, applied to the project in order to receive the data from the hardware.

Mjølner’s Bluemix team (specific developers that have experience with the platform) worked on the project, and they developed the cloud application for both backend and frontend.

Mjølner’s software architect on the project collected all the dots in this collaboration. He compiled an understanding of the technical and practical installations of Carlsberg, how to match the hardware that Arrow developed with the available data, whether they could place the hardware where it needed to be placed, and so on.

Arrow’s IoT Solution Architecht designed and built the hardware required for the two PoCs including temperature measurement, GSM modem for sending the data to the cloud, GPS tracking, and a battery backup in case of a power breakdown.

“This IoT project has opened our eyes to new opportunities in terms of operations and streamlining.”

cloud based platform

Soon after the team concluded their work on the PoC, they set up the sensors on the beer tanks in Telia Parken and displayed the incoming data to Carlsberg.

In this PoC, data (temperature) comes in via Watson Internet of Things to the Bluemix platform from the sensors on the beer tanks. A database (Bluemix) saves the data. The backend analyzes the data and calculates if there is an alarm situation for which data is prepared for presentation on a frontend.

IBM’s Bluemix is a cloud platform that makes it possible for Mjølner’s developers to create this set-up much easier than if they had to create it all from scratch. It includes multiple APIs (Application Programming Interfaces), that is, ways in which the developer easily can integrate what he wants. That is the value of Bluemix. It is available and ready to use in the developers application.

In this PoC, Cloud means that the team can create the project without collaborating with Carlsberg’s IT department. The system does not run on a machine inside Carlsberg’s facilities, rather, it runs in the cloud. This is one of the biggest revolutions of cloud.


The value of the PoC for Carlsberg comes in reduction of loss and optimization of services. The team of IBM, Arrow, and Mjølner has shown Carlsberg that the two projects are possible, cost-effective, and do-able through an IoT platform.

The technical development of the PoC is a success, and the installations function as intended. The sensors react and send data.

The interesting question now is: where do we go from here? What is Carlsberg going to use this new opening of opportunities via an IoT platform for? The possibilities seem endless.


The Carlsberg Group is the fourth largest brewery group in the world. It is founded and headquartered in Copenhagen, Denmark.

The company’s flagship brand is Carlsberg Beer, but it also brews Tuborg, Kronenbourg, Somersby cider, Russia’s best-selling beer Baltika, Belgian Grimbergen abbey beers, and more than 500 local beers. Carlsberg employs around 45.000 people.
