The Biomonstaaar algae bioreactor is an open source, automated photobioreactor (PBR) array with future applications for genetic engineering, bioremediation, and space research. It consists of an upright cylinder column with mounted sensors for monitoring key aspects of the culture's health such as pH, temperature and dissolved O2. The sensors are integrated with a Raspberry Pi - Arduino microcontroller system which provides a Graphical User Interface (GUI) for users to view the sensor data and operate the bioreactor from a Web browser. We're still in the process of adding instructables for the reactor systems, so make sure to follow our collection for updates!
