“Designing an Economic IOT Based Device Prototype for Monitoring Marine Environment’’

In modern days, the wide range of unexploited resources submerged under the river or ocean aquatic environment requires new research. Group of Experts on the Scientific Aspects of Marine Pollution (GESAMP) estimated that, up to 40 percent of the world's marine environment is polluted by 60-95% of the wastages. To reduce the pollution, the

distance of waste from the shore has to be measured first. This work focuses on developing a wireless, power-efficient, underwater IoT based device to measure, monitor

and surveil underwater environments. Internet of Things (IoT) can be a great tool to achieve this goal of connecting devices everywhere at any time. Firstly, a physically

sensible, water resistant, low power consuming model of the device is developed. Next, a wireless system of universal asynchronous reception & transmission communication

(UART) between the device and a central database was developed where all the collected information is presented with a graphical interface and a dynamic table is designed. The device and the database are interconnected through Wi-Fi and this device can be operated by user through a website from any electronics device connected to the internet. Lastly, the power optimization problem of the designed device is reduced from less to minimum under the circumstances of a manual deep sleep-awake scheme.
