A Wireless Low Cost, Power Efficient & Multipurpose Underwater Sensor Node (UWN) for Monitoring Ambient Aquatic Environment

Presently Sensor Node technology has grown enough to be used in any adverse environment, and the appearance of new physical sensors has increased the range of parameters for gathering data. The enormous amount of unexploited resources drowned under the water (river, ocean) environment urges the need for new vital research in the field of sensors and hybrid sensor nodes. This work focuses on utilizing a wireless, power-efficient underwater sensor node to measure, monitor, surveillance aquatic environments. Presently there is a globally growing demand across all industries for small and portable electronic devices that feature internet connectivity, which is primarily due to their ease of use provided by vigorous interoperability and practicability in almost any situation. Internet of Things (IoT) can be a great tool to achieve this goal of connecting devices everywhere at any time. In this thesis-Firstly, A physical functional model of sensor node (SN) is developed. Next, A wireless monitoring system establishing asynchronous transmission and reception communication (ATRC) is designed between the sensor node and a central database where all the collected information is presented with a graphical interface. The node and the database are interconnected through IoT and this sensor node can be operated by user through a website with any electronics device connected to the internet.
