Let’s have a closer look on hardware. In his project he uses these components:

Raspberry Pi functions as a processing unit combined with our UniPi board controller which provides necessary inputs and outputs. HDMI 7’’ touchscreen display gives access to GUI while digital air/fuel ratio controller gives system necessary info when to let more air into the boiler. Centrifugal fan then regulates the air/fuel ratio as is necessary.

System uses custom made scripts written in python (using version 2.7) along with EVOK software. GUI is very simple as can be seen below.
