DESIGN AND CONSTRUCTION OF WATER LEAKAGE DETECTOR

Abstract

This project is design and constructed as a water leakage detector which is an instrument that indicates the level as well leakage of water .Water leilkage .detection is noticed or seen base on the variation of the resistance. A float made of wood on the surface of th e water is attached to a variable resistor. As the water reduces the float draws down the slide contact and th-e I changes in resistance is shown on a seven segment display. This is achieved by using a special form of a variabie resi~!~r called potentiometer. It has three terminals. Two terminals are conne ::ted to the opposite sides of the resistive element and the third con ects to a sliding contact that can be adjusted as a voltage divided. The idea was borne out of the need to have knowledge of the quantity of water in a tank and to avoid water leakag(~ in a tank or other water storage vessels. The project was carried out using commonly available and inexpensive component6 and the result obtained were satisfactory.
