ABSTRACT
In this project we introduce the notion of liquid
level monitoring and management within the context of electrical conductivity
of the liquid. More specifically, we investigate the microcontroller based liquid
level sensing and controlling in a wired and wireless environment. Liquid Level
management approach would help in reducing the home power consumption and as
well as liquid overflow. Furthermore, it can indicate the amount of liquid in
the tank that can support Global liquid types including cellular data loggers,
satellite data transmission systems for remote liquid monitoring system.
Moreover, cellular phones with relative high computation power and high quality
graphical user interface became available recently. From the users perspective
it is required to reuse such valuable resource in a mobile application.
Finally, we proposed a web and cellular based monitoring service protocol would
determine and senses liquid level globally.
