Drain Alert for Sewage Treatment Plant with SMS & GPS Location

Intelligent Sewage Monitoring System with Arduino Nano

Project Overview

This report details an intelligent sewage monitoring system built using an Arduino Nano microcontroller. The system monitors various parameters critical for sewage system health and alerts users via SMS in case of anomalies.

Components

• Arduino Nano: The primary controller for the system, processing sensor data and triggering actions.
• Ultrasonic Sensor: Measures the distance to the water surface, providing water level data.
• LCD Display (optional): Provides real-time readings on-site (water level, sensor status).
• Water Level Sensor: Detects the presence of sewage water.
• Gas Sensor: Detects the presence of harmful gases.
• GPS Module: Determines the system’s geographical location.
• GSM Module: Enables cellular communication for sending SMS alerts.
• LM2596 Module: Steps down 220V AC to 5V DC for powering the system.

Functionality

1. System Startup: Upon powering on, the system utilizes the LM2596 module to convert 220V AC to 5V DC, powering the Arduino Nano and other components.
2. Initial SMS: The Arduino sends an SMS to two pre-defined mobile numbers upon startup, indicating successful system connection.
3. Continuous Monitoring: The system continuously monitors:
   • Water Level: The ultrasonic sensor measures the distance to the water surface. If the water level falls below a pre-defined threshold (e.g., 10 cm), an alert is triggered.
   • Sewage Water: The dedicated water level sensor detects the presence of sewage water. If sewage water is detected, an alert is triggered.
   • Gas: The gas sensor detects the presence of harmful gases. If gas is detected, an alert is triggered.
4. Alert Generation: In case of any anomaly (low water level, sewage water detection, gas detection), the system triggers an SMS alert.
5. SMS Content: The SMS alert includes:
   • GPS Location: The GPS module provides the system’s geographical coordinates, embedded as a link within the SMS. Clicking this link opens the location on Google Maps.
   • Sensor Information: The SMS displays the current water level (obtained from the ultrasonic sensor), sewage water presence (detected by the dedicated sensor), and gas detection status.

Benefits

• Real-time Monitoring: Continuous monitoring of critical sewage system parameters allows for proactive maintenance and timely intervention.
• Remote Alerts: SMS alerts with GPS location enable swift response to issues, regardless of user location.
• Improved Efficiency: Early detection of problems helps to prevent costly system failures and environmental damage.

Future Enhancements

• Data Logging: Implement data logging features for long-term analysis of trends and potential optimization strategies.
• Cloud Integration: Integrate with cloud platforms for remote data visualization and advanced analytics.
• Web Interface: Develop a web interface for users to access real-time sensor data and historical trends.
• Multiple Sensor Support: Integrate additional sensors for comprehensive monitoring (e.g., pH level, flow rate).

Conclusion

This intelligent sewage monitoring system effectively utilizes Arduino technology to create a cost-efficient and reliable solution for remote monitoring and alerting. The system empowers users with real-time data and timely notifications, enabling proactive maintenance and improved sewage system management.
