Overview:

The Water Level Monitoring System is an IoT-based solution designed to monitor the water level in tanks, reservoirs, overhead tanks, sumps, rivers, or dams in real-time. It detects water levels using ultrasonic sensors or float sensors and sends data to a web dashboard or mobile app. The system alerts users when the water level crosses minimum or maximum thresholds, helping in preventing overflow, managing water supply, and detecting drought or flood conditions.

Key Features:

• Real-Time Monitoring:
  Continuously measures water level and sends updates at fixed intervals.

• Instant Alerts:
  Sends SMS/app/email alerts when water level is too low or too high.

• Remote Access Dashboard:
  View current water levels, usage history, and trends from any location.

• Auto Pump Control (Optional):
  Automatically starts or stops the water pump based on tank levels.

• Historical Data Visualization:
  View trends and reports to analyze usage patterns.

Technology Stack:

• IoT Hardware:

  • Sensor: Ultrasonic Sensor (HC-SR04) / Float Sensor / Water Level Sensor

  • Microcontroller: ESP8266 / Arduino Uno / ESP32

  • Connectivity: Wi-Fi (ESP8266) or GSM module (SIM800L) for remote alerts

  • Actuators (Optional): Relay module for automatic pump control

• Backend:

  • PHP / Java / Node.js to store sensor data, manage thresholds, send alerts

  • REST API for communication between device and dashboard

• Frontend:

  • HTML, CSS, Bootstrap, JavaScript for dashboard UI

  • Mobile app (optional): Hybrid app using JavaScript or Android (Java)

• Database:

  • MySQL / Firebase / MongoDB to store water level logs and alert history

Modules:

1. Sensor Module:
   Gathers real-time data on the water level in the tank or reservoir.

2. Threshold Management Module:
   Allows admin to set min and max water level thresholds for alerts.

3. Alert Module:
   Sends notifications to registered users when level goes out of bounds.

4. Pump Control Module (Optional):
   Uses relay to automatically turn pump ON/OFF based on thresholds.

5. Data Visualization Module:
   Line graphs or bar charts show usage trends and past levels.

6. User Management Module:
   Allows multiple users to access different tanks/reservoirs.
