Water tank maintenance system.

Abstract

This project combines a dirt sensor, ultrasonic sensor, servo and DC motor with an Atmel chip the 8-bit ATMega328PU microcontroller in 28 pin DIP package, with double flash space and an HD44870 character based LCD- JHD162A to make it easy for the user to monitor the bottom settled dirt in water tank. The overarching goal of this project is to detect and monitor water storage tank status and raise awareness about presence and accumulations of water foreign in water storage tank contaminates its water leading to water-borne infections. Detecting and monitoring dirt level and water volume makes it easy to determine dirt accumulation across a period and is accurate in terms of total usage. Both the dirt level and water volume are displayed on an LCD. This project was therefore aimed at developing a water tank maintenance system that would solve the above problem through the following ways; displaying the amount of settled dirt at the bottom and water volume in the tank, it also cleans the tank using a cleaning machine attached with a brush which rotates through 360 degrees for 10 seconds and automatically opens an outlet to draw dirty water for 10 seconds, finally, it notifies the user about water storage tank status. The work is arranged mainly in six chapters, Chapter one includes the introduction of a water tank maintenance system. Chapter two discusses the literature related to the system, Chapter three illustrates the methodologies used in coming up with the working prototype of the system, Chapter four includes system design and analysis, Chapter five contains the implementation and testing of the system and chapter six contains the summary of the work, discussions and recommendations.
