This proposed automated water testing kit is to check the water parameters of multiple ponds within a short time and with low cost. It will be based on Internet of Things (IoT), AI and Machine Learning (ML). The proposed kit is able to collect real-time data from multiple ponds, Hydroponics and Aquaponics, analyze and display them on an easy-to-use platform for monitoring purpose. It can measure pH, ammonia, nitrate and nitrite level of particular water bodies as these are the vital indicators of water quality for smart fish farming. It can also pre-process acquired data by the onboard processor (Raspberry pi) and transfer to the cloud for determining the water quality. Users can monitor water quality regularly as a graph and other means by logging in their web account. The kit has been tested thoroughly to ensure its accuracy and usefulness. The proposed remote sensing kit can be seamlessly integrated into the water management system of the metropolitan area and can be considered as an important part for the future smart city concept.
