Abstract

In this study, a low-cost RGB sensor is developed to measure online the microalgae concentration within a photo-bioreactor. Two commercially available devices, i.e., a spectrophotometer for offline measurements and an immersed probe for online measurements, are used for calibration and comparison purposes. Furthermore, the potential of such a sensor for estimating other variables is illustrated with the design of an extended Luenberger observer.

摘要

在本研究中，开发了一种低成本的RGB传感器，用于在线测量光生物反应器内的微藻浓度。使用两种市售设备，即用于离线测量的分光光度计和用于在线测量的浸入式探头，进行校准和比较。此外，通过扩展的Luenberger观测器的设计，展示了这种传感器估计其他变量的潜力。
