However, its high energy need in the cultivation process, the prevalence of manual work and the high costs deem the production and commercialization of it difficult. Consequently, the challenge of artificial microalgae production is not only to replicate and enhance the optimum natural growth conditions, but to make it automated and profitable. The purpose of this research was to develop an automated system to monitor and control specific growth conditions in order to improve the algae biomass production process. This research required the planning and installation of a control cabinet on a flat plate photobioreactor, components selection, installation of sensors and software programming in LabVIEW. The result of this research was a system that monitors the basic environmental growth parameters, which are temperature, light and pH. In addition to the monitoring system, a control system for light and CO2 flow was integrated to simulate specific growth conditions of microalgae. Further research is required in order to strengthen the idea of a fully automated flat plate photobioreactor for a more efficient microalgae cultivation. This approach may lead to a technology that can be used as a base model for future applications on more reactors.
