One of our Swedish customers has created an automated wood chip boiler system.
One of our Swedish customers has found and created an automated wood chip boiler system. In his project he uses these components:
- Raspberry Pi
- UniPi Board
- HDMI 7’’ touchscreen display
- Digital Air/fuel ratio controller
- Centrifugal fan
- 3 DS18B20 Temperature sensors
- A k-type Temperature sensor (for high temperatures 0-1000℃)
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. A centrifugal fan then regulates the air/fuel ratio as is necessary.
The system uses custom scripts written in python (using version 2.7) along with EVOK. GUI is very simple as can be seen below.
