Multilevel Water Level Control & Monitoring of Multiple Tanks

Abstract

The traditional method of water tank overflow indication is to insert one pipe in the tank and whenever the tank is completely filled the water starts flowing through this overflow pipe this indicates that water tank is completely filled and the pump should be turned off. But this shows only tank filling status and does not indicate different heights or levels of water in the tank.In this project water level of 4 tanks is monitored and controlled by controlling the motor which pump the water from reservoir to tank. For sensing water level float is used as sensing element. One float switch will sense one water level therefore for sensing 4 different water levels 16 float switches are used. Microcontroller 8051 is used for expansion of tanks. Therefore water level of many tanks is monitored and controlled. All these information is provided to ESP8266 Wi-fi module which is prefabricated arduino board.ESP8266 is used for controlling motor driver circuit and uploading data to server by inbuilt Wi-Fi unit. This project can be used in multi-storied buildings where tanks are situated at high places knowing the tank filling status is difficult. The user can control the water level manually if given access through admin by turning on/off motors which pump the water from reservoir to the tank. Otherwise guest user can only monitor the status of tanks which are made visible by admin for guest user.By doing all these practices the traditional work of water level controlling becomes much easier, people sitting at remote place form the tanks system can easily do the job of water level controlling and monitoring for in house as well as industrial applications.
