Water Level IndicatorProject
An Eco-friendly Smart Water
Management System
Engineering Project Presentation
2.
Introduction
• • Wateris one of the most important natural
resources.
• • Overflowing tanks waste water and energy.
• • The Water Level Indicator helps monitor and
control water usage.
3.
Objective
• • Todetect and display water levels in a tank.
• • To prevent overflow and save electricity.
• • To automate the motor ON/OFF process.
4.
Components Used
• •Transistor (BC547) – acts as a switch
• • LEDs – indicate water levels
• • Resistors – control current
• • Battery (9V) – power source
• • Water Tank and Probes – for sensing
5.
Circuit Diagram
• •Multiple probes are placed at different levels
in the tank.
• • When water touches a probe, the circuit
completes and LED glows.
• • Each LED shows the corresponding water
level.
6.
Working Principle
• Watertouches first probe → LED1 glows
