With the increasing of world population and the proportion of extreme climates, there is an urgent demand for food, sustainable water sources, green energy, and health maintenance. This patent is promising to contribute to the related industries with the design to adjust the number of sensors and stabilize the sensing electrodes by two layers of fixing plates in water reactor. The sensor placement holes of the upper and lower fixing plates are different in size. The best sensing orientation is achievable when the water level gradually drops. The vertical partition of plate can block the bubbles that interfere with the surfaces of electrodes. Therefore, this system can effectively read the data from water and then transmitted to the cloud. This system will alert users when the environment state exceeds the range of growth parameters. By approaching intelligent judgment, automatically control of the operation parameters is achievable for maintaining the best growing environment.

This system is designed to adjust the number of sensors and stabilize the sensing electrodes by two layers of fixing plates. The vertical partition of plate can block the bubbles that interfere with the surfaces of electrodes. Therefore, this system can effectively read the data from water environment, and then transmit data to the cloud. Through automatically control the operation parameters by approaching intelligent judgment, sustainable use of water and resources is achievable. This system can not only enhance biomass energy production of microalgae, real-time monitor the quality changes of water, but also circulate and regenerate water resources.

Microalgae converts fixed CO2 into carbohydrates by photosynthesis, and the advantages of microalgae are fast growth and high carbon fixation capacity, and the composition of algae oil and diesel and fuel oil are similar, suitable for the development of mass diesel and aircraft fuel, and the cell wall polysaccharides are easier to decompose than cellulose and can be used to produce biomass alcohol. Therefore, it is a global trend to use microalgae as a raw material to generate biomass energy. In addition, in addition to algae energy recovery, biotechnology can be used to replant and make The additional products increase the economic value and application of biotechnology. The HMF produced by microalgae can be as high as 6000 US dollars per kilogram.
