🚀 Key Components

1. Sensor Module

The Sensor Module is responsible for measuring the liquid level in the septic tank and transmitting the data wirelessly.

Hardware:

• JSN-SR04T (IP68 Ultrasonic Sensor):
  Measures the distance from the liquid's surface to the bottom of the tank using ultrasonic waves.
• LoRa SX1278 Module:
  Transmits measured data wirelessly to the Monitoring Module using long-range, low-power communication.
• Arduino Uno R3:
  Handles sensor readings and data transmission.

Functionality:

1. Ultrasonic waves are sent and received by the JSN-SR04T sensor to calculate the distance:
   distance = duration * 0.034 / 2
2. The distance is adjusted to account for the tank's configuration and converted into remaining capacity.
3. Data is transmitted via the LoRa SX1278 module to the Monitoring Module.

Code Workflow:

duration = pulseIn(echoPin, HIGH); // Trigger Ultrasonic waves
distance = duration * 0.034 / 2;  // Calculate distance in cm
LoRa.print(distance);  // Transmit data

2. Monitoring Module

The Monitoring Module processes incoming data, calculates the septic tank's capacity percentage, stores it in a database, and notifies the user of critical conditions.

Hardware:

• ESP32:
  Acts as the processing hub and communication gateway.
• LoRa SX1278 Module:
  Receives data from the Sensor Module.
• SIM800L EVB GSM Module:
  Sends SMS alerts for critical tank levels.

Functionality:

1. The capacity percentage is calculated from the received distance data:
   Capacity % = ((SepticTank_Height - distance) * 100) / Septictank_Height
2. Data is sent to Firebase Realtime Database, including:
   • Capacity percentage
   • Unix timestamp
   • Human-readable date
3. If the capacity exceeds a defined threshold, an SMS alert is sent to the user.

3. Web Application

The Web Application visualizes the septic tank data and provides predictive insights for efficient management.

Technologies:

• Frontend: HTML, CSS, JavaScript
• Backend: Firebase Realtime Database

Features:

1. Dashboard:
   • Doughnut Chart: Displays the current tank capacity percentage.
   • Historical Graph: Shows trends over time.
   • Prediction Algorithm: Estimates when the tank will be full based on historical data.
2. Dynamic Rendering:
   • Automatically adapts to display data for multiple tanks associated with the user.
3. User Authentication:
   • Secure login ensures data privacy and personalized access.
4. Real-Time Updates:
   • Septic Tank data updates instantly via Firebase integration.
5. Alerts:
   • SMS notification for critical capacity level.

Why It Stands Out:

• Interactive Visuals: Makes data easy to understand.
• Predictive Analytics: Helps you plan ahead and avoid emergencies.
• Scalable Design: Supports monitoring of multiple tanks seamlessly.

⚙️ How It Works

1. Data Collection:
   • The Sensor Module measures the liquid level and sends data to the Monitoring Module via LoRa.
2. Data Processing:
   • The Monitoring Module calculates the capacity percentage and stores it in Firebase.
3. User Notifications:
   • SMS alerts are sent when the capacity exceeds a critical threshold.
4. Web Visualization:
   • The Web Application fetches and displays data dynamically, with visual insights and predictions.

🔒 Security and Scalability

• Authentication:
  User login ensures secure access to data.
• Dynamic Rendering:
  Personalized views for each user, with scalability for multiple tanks.
• Firebase Integration:
  Real-time, secure, and reliable data storage.

📈 Key Benefits

• Remote Monitoring: View your septic tank's status anytime, anywhere.
• Actionable Insights: Predict when your tank will need maintenance.
• Critical Alerts: Stay informed with timely SMS notifications.
• User-Friendly Interface: Simple and intuitive design for ease of use.
