Water Tank Control System

A real-time water tank simulation and control system built with C++ demonstrating advanced Object-Oriented Programming concepts and system automation.

Overview

This project simulates an automated water tank management system with intelligent pump control, water level monitoring, and manual override capabilities.

Features

Automated Control

• Smart Pump Management: Automatic pump activation/deactivation based on water levels
• Real-time Monitoring: Continuous water level tracking with percentage display
• Alert System: Critical alerts for low water (< 10%) and overflow risk (> 95%)
• Simulation Engine: Random water consumption pattern for realistic testing

Manual Control

• Manual Pump Control: Direct ON/OFF pump operation
• Override Mode: Disable automatic control for maintenance or testing
• Cycle Control: Run single or multiple simulation cycles

Safety Features

• Low water threshold detection (< 30%)
• High water threshold detection (> 90%)
• Critical level alerts with visual warnings
• Overflow prevention mechanism

Technologies Used

• C++
• Object-Oriented Programming (OOP)
• System Simulation & Control Logic
• Random Event Generation

OOP Concepts Implemented

Inheritance

SystemComponent (Base Class)
    ├── WaterSensor
    ├── PumpControl
    └── Controller

Key OOP Principles

• Abstraction: Pure virtual function in SystemComponent base class
• Inheritance: All components inherit from SystemComponent
• Polymorphism: Virtual displayStatus() method overridden by each component
• Encapsulation: Private data members with controlled access
• Composition: Controller contains WaterSensor and PumpControl objects

How It Works

1. Water Sensor: Monitors water level (0-100%)
2. Pump Control: Manages pump state (ON/OFF) with override capability
3. Controller: Coordinates sensor data and pump operations
4. Automation Logic:
   • Level < 30%: Pump turns ON
   • Level > 90%: Pump turns OFF
   • Pump adds 5% water per cycle when ON
   • Random consumption: 0-2% per cycle

Menu Options

1. View Status          - Display current water level and pump state
2. Run 1 Cycle         - Execute one simulation cycle
3. Run 10 Cycles       - Execute 10 consecutive cycles
4. Manual Pump ON      - Turn pump on manually
5. Manual Pump OFF     - Turn pump off manually
6. Enable Override     - Disable automatic control
7. Disable Override    - Re-enable automatic control
0. Exit                - Quit program

How to Run

g++ water_tank_simulation.cpp -o water_tank
./water_tank

Sample Output

[Water Sensor] Level: 65%
[Pump Control] Pump is OFF

[Water Sensor] Level: 28%
[Pump Control] Pump is ON

!!! ALERT: Water critically low !!!
