Fabrication of Liquid Tank Automation System

Abstract

Generally most of the houses and industries depend upon the overhead tanks as the main source of water. People generally switch on the motor when their taps go dry and switch off the motor when the tank starts overflowing. This results in unnecessary wastage of water and sometimes non-availability of water in emergency. This phenomenon is commonly seen in both Urban and rural areas and this needs to controlled by monitoring water level in the tank, here we need a mechanism capable of switching on the motor when the water level in the tank goes low and switching it off as soon as the water level reaches a maximum level. Automatic water level control can be achieved by monitoring and keeping track of water level with the help of electronic sensors and controllers. Float switch is used to monitor the water level. Water level obtained from float sensor is given to Arduino, where all the calculations and decisions are made. Arduino generate a signal to turn on/off the motor based on water level. This on/off signal and the water level should be communicated to the motor by using relay module. The motor will be controlled automatically based on the water level in the tank. Some of the advantages of Automatic water level control system in overhead tanks are Automatic system replaces human intervention and provides hassle free maintenance, prevents wastage of water, efficient usage of water and energy resources.
