One of our Swedish customers found an excellent use for UniPi board controller. He has created a smart controller for wood chip boiler. His project called openBC is opensource and he works on it in his free time.
Let’s have a closer look on hardware. 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
- 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. 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.
We are always glad whenever our product can be part of some great project and are always willing to find out more. If you have an interesting project you want to share with us contact us at firstname.lastname@example.org.
