Dissolved oxygen in litopenaeus vannamei shrimp ponds is very important. When the dissolved oxygen content is unstable and low, it will cause many problems such as slow shrimp growth, little or slow eating, and excess food in the shrimp pond, pathogens increase and the survival rate of shrimp also decreases. Currently, people in the Southeast region of Vietnam mainly farm according to traditional farming processes, using oxygen supply systems with bottom aeration systems and water fans, consuming a lot of electrical energy and water, it is difficult to control dissolved oxygen content in ponds. This paper introduces a novel architectural model for the ultrafine bubble (UBF) system to increase oxygen content in shrimp ponds using IoT technology. This proposed system allows to measurement oxygen concentration automatically and real-time monitoring of oxygen content in the shrimp farm as well as automatic control of the ultrafine bubble system (UFB) to always ensure the best amount of oxygen in a pond for shrimp to grow. The proposed model helps save electricity, reduce human labor, and improve shrimp production and get benefits for shrimp farms.
