Tank Water Level Monetring System

This project helps on monetoring the water level on the tank with the help of Ultrasonic Sensor. Arduino is used as a controller and LCD display is used for displaying information. For alert purpose a buzzer is used whose alert can be set in the level wanted. Notifies when there is low water level and also when the tank is about to fill fully.

Programming Language: C++

List of components

• Arduino UNO
• LCD LC2 Display
• Untrasonic sensor
• Jumper Wires
• Buzzer
• Battery Litheum Ion (5V or 12V)
• Ply Wood/Stick

Please adjust the height of the tank in the code as the height of tank may be different as used in this project. and replace the alert level based on calculation. And the display used in this project is connected by I2C module whose diagram is not shown in circuit diagram
