Microcontroller based Automatic Water level Control System

Water scarcity is one of the major problem facing major cities of the world. Major problems regarding that are when either sump or bore well motor is started people forget to switch OFF these motors so water goes waste as well as electricity gets consumed. There is not fix schedule to start and stop motors so there is always problem of unwanted vacancy of water in overhead tank, people are facing such problems at midnight & situation becomes critical. Sumps as well as bore well motor can dry run giving electricity wastage. So overall wastage has been identified as a major culprit; this is one of the motivations for this research, to deploy computing techniques in creating a barrier to wastage in order to not only provide more financial gains and energy saving, but also help the environment and water cycle which in turn ensures that water is saved for our future. This paper presents research in embedding a control system into an automatic water pump controller through the use of different technologies in its design, development, and implementation. The system used microcontroller to automate the process of water pumping in an over-head tank storage system and has the ability to detect the level of water in a tank, switch ON/OFF the pump accordingly and display the status of motor on LED. This research has successfully provided customized solution to society an improvement on existing water level controllers by its use of calibrated circuit to control automatic water level and use of DC instead of AC power thereby eliminating risk of electrocution.
