Oxygen enrichment device is designed to be easily transported to enclosed and shallow water bodies to enhance the dissolved Oxygen (DO) levels throughout these areas. Two bilge pumps, mounted on a small-size pontoon, help create surface water turbulent to increase oxygen transfer between air and water. The ESP32 microcontrollers with peer-to-peer WiFi communication capability are used as the main controllers of this low-cost oxygen enrichment device, so that manual motion control of the pontoon can be achieved as well as sensor-data and device statuses can be monitored using a two-way WiFi communication between the remote control and the portable pontoon. The DO content in an immediate vicinity can be improved up to 18% on average after this device is operated in place for at least 13 minutes. The data visualization of this device recorded route and DO sampling locations in a confined, shallow pond in front of the Faculty of Engineering Building, Thammasat University, can be analyzed for further planning of the water-quality.
