The primary goal of this project is to design and build a wireless sensor network system for monitoring water bodies for saving underwater life.The main source of pollution in the water bodies is excess level of nitrogen and phosphorous that results in degradation of oxygen level that is very dangerous for penguins, whales, sharks, etc inside the sea. The pollution monitoring is very important for saving ocean animals. In this a solar-powered sea pollution monitoring, system has been proposed the main goal of this system is tracking and measuring of different parameters that gives the measure of different water quality parameter and the end user are able to determine whether that water is suitable for marine life or not. The proposed system employs the use of IoT to make real-time data freely available across a wide area, and it is a very good solution for monitoring the weather for aquatic animals. The system monitors climate change inside water such as temperature of water, rain, moisture, light intensity, UV radiation, and even airborne carbon monoxide levels. These all parameters are responsible for increasing the acid level inside water. This acid level will results the reduction in oxygen level. The data from these sensors is sent to the server and displayed as graphical statistics. The information posted on the web server is easily accessible from anywhere, and the information gathered through these servers can also be used as a reference for taking the necessary action for problem solution. The project also includes an app that sends messages as a useful alert system to notify people also about the sudden weather changes of the coastal areas. The use of an API to analyse sensor data and forecast an accurate result in order to predict more sophisticated weather forecasts. It is a compact structure and having fewer moving parts, this design requires less maintenance. The components of this project are solar-powered and make use of rechargeable batteries and require little maintenance. All readings are displayed on an LCD display in prototype and send to server side. Every movement of our system is controlled by an Arduino micro controller from server side.There are many chemical and biological factors of water that affect the production of fish. India is the country of rivers and ponds.If the proper managements of rivers and ponds have been done with the help of this system than this system is very much useful for the production of fish and fulfilling the demand of food in future.
