Nature of project: experimental, experimental
Available to students on full-time physics degree schemes or joint students.
This project is to construct, build, program and test an analyser for flue gasses coming from a charcoal kiln. The analyser will be based around an Arduino microcontroller in conjunction with an appropriate display and sensors.
The device should use standard off-the-shelf low cost sensors to determine the temperature, humidity and concentration of volatile compounds at the tip of a probe. The results should be displayed on the built-in display in a useful format.
The student will need to design the system, specifying appropriate gas sensor devices as well as the display. The project will involve designing and 3D printing a suitable housing for the control, display and probe.
A successful project will develop beyond the above in one/some of the following directions:
A more advanced probe could be added to the system allowing display of specific volatile compounds and flue gasses such as carbon monoxide.
Another extension to the project would be to give the possibility of running the sensor system in datalogging mode whereby results from the sensor outputs are logged to a text file on an SDcard along with timestamp information.
When considering where to take your project, please bear in mind the time available. It is preferable to do fewer things well than to try many and not get conclusive results on any of them. However, sometimes it is useful to have a couple of strands of investigation in parallel to work on in case delays occur.
This project is only available as a Y3 project.
Please speak to Dave Langstaff if you consider doing this project.
Initial literature for students:
The project will require assistance from the electronics workshop. Although the Arduino micro-controller and display are ready assembled, the student will need to design a suitable case and probe housing. There will be a small amount of soldering involved during the construction of the instrument.
