One of the Precious and important resource in the earth maybe water. Now a days people need everything happen smarter other than olden days techniques used. In this project ultrasonic sensor-based tank water level monitoring system (sense and monitor). The Main objective is to have a sensor which detects the level of water and it should display on LCD which is currently available in the tank. The Ultrasonic Sensor is placed at the top of the tank in which we will measure the level of water. The Major requirement would be Ultrasonic sensor which senses level of water (%) from the top of the tank. The main controlling device of the project is Arduino which loaded program written in embedded C language. Arduino can continuously read the water level in tank using ultrasonic sensor will be display on LCD. There is a mode selection switch, which to select the manual and automatic operation of the water pump. Ultrasonic sensor is used for automatic switching of water pump and Button is used for manual controlling of water pump ON/OFF. Based on the water level and user input, Arduino will turn ON/OFF the water motor automatically. Here we are using AC bulb as water motor. To achieve this task Arduino loaded program written in embedded C Language.          

Objectives:

1. To develop an ultrasonic sensor-based water tank monitoring system.
2. To measure the water level inside the tank using an ultrasonic sensor.
3. To display the current water level in percentage (%) on an LCD.
4. To use Arduino as the main controller for monitoring and controlling the system.
5. To provide manual and automatic modes for water pump operation using a mode selection switch.
6. To automatically turn ON/OFF the water pump based on the detected water level.
7. To provide manual control of the water pump using push buttons.
8. To reduce water wastage and avoid overflow of the tank.
9. To improve water management through a simple and efficient automated system.
