Abstract [en]

The purpose of this project is to build a prototype biogas plant with a cheap control system. The plant is a prototype of a real plant, onto which the control system is to be attached in the future. The prototype does not produce gas, since it has water and air as input substances. The substances are however controlled in the same way as in a gas producing plant. The plant is built mostly of garden hose equipment and plastic buckets. The control system consists of several Arduino Nano which reads sensor values and process the data. All necessary sensor values are displayed by a computer on a graphic interface written in Labview.  

The result was a functional control system with some issues as unbalance between outflowing and inflowing amount of water in the digester, difficulties with calibration of the temperature sensor. Therefore it needs further work and testing before attaching on the real plant.
