Design and Development of a Level Sensor

Water is one of the most essential nature's gifts to the manhood and without water no one can imagine their lives. Now man recognized the water significance, particularly where water is not easily available [1]. Now this is being achieved in an appropriate manner in city areas where the use of water is more than its availability [2]. One of the inspiration is to organize computing techniques in creating a barrier to wastage in order to, not only provide more economic gains and energy saving, but also helps the environment and water cycle which in turn guarantees that we save water for our future [3]. There are several problems of electricity in rural area. Also the small towns are incapable to use electricity based level sensors in small industries or domestic tanks. This paper describes the design and implementation of water level sensor prototype without power supply. The sensor consists of low cost materials. Hence sensor is cost effective, reliable and could be made easily available in rural area.
