What is it about?
In a previous article (Perspectives of optical colourimetric sensors for anaerobic digestion), I discussed how colour-based dye sensors can be used to detect specific parameters during the production of biogas. Here, I have written a short article describing the method for determining the observable changes in the dye colours. This method allows the digitalisation of the dye colour changes so the user can qualify them. The data can then be computationally processed for interpretation.

Why is it important?
This is important because it gives the user the required methodology to differentiate between various chemicals within the biogas production process, giving the operator a better understanding of the biological processes occurring within the reactor. Also, this is a much more affordable technique for the detection of different chemicals because it can measure many variables at once, it does not require large equipment and all the necessary parts can be purchased over the counter. This will improve the ability for operators of low-cost biogas plants to have better monitoring of their system to avoid biological process failure, all at a low cost.
