Water-Quality-Monitoring-Project

A real-time water quality monitoring system using Arduino Nano to measure TDS, EC, and temperature, with results displayed on a 16x2 I2C LCD. Ideal for sustainable water management and analysis.

Sustainable Water Quality Monitoring System with Arduino Nano

This project is designed to monitor water quality in real-time by measuring Total Dissolved Solids (TDS), Electrical Conductivity (EC), and Temperature using an Arduino Nano. The system displays the readings on a 16x2 LCD with I2C interfacing for easy monitoring and decision-making regarding water quality.

Features

• Real-time water quality monitoring.
• Measures TDS, EC, and Temperature.
• Displays data on a 16x2 I2C LCD screen.
• Utilizes a TDS sensor and digital temperature sensor.
• Simple and cost-effective solution for water quality management.

Components Used

• Arduino Nano: Microcontroller for processing data.
• TDS Sensor: Measures Total Dissolved Solids in water.
• Temperature Sensor: Measures water temperature.
• 16x2 LCD with I2C: Displays the sensor data.
• Jumper wires, Breadboard: For connecting the components.

Installation

Libraries Required:

• DallasTemperature: For interfacing with the temperature sensor.
• OneWire: For communication with the Dallas temperature sensor.
• LiquidCrystal_I2C: For displaying data on the LCD screen.

You can install these libraries via Arduino IDE:

1. Open Arduino IDE.
2. Go to Sketch > Include Library > Manage Libraries.
3. Search for each library by name and click Install.

Code:

• Clone this repository or download the files.
• Open the WaterQualityMonitor.ino file in the Arduino IDE.
• Select your board and port under Tools.
• Upload the code to the Arduino Nano.

Steps to Use This Code in the Arduino IDE:

1. Create a New Folder:

   Create a folder with a name like TdsReader. Arduino requires the .ino file to be in a folder with the same name.

2. Save the File:

   Save the file as TdsReader.ino inside the TdsReader folder.

3. Open in Arduino IDE:

   Open the TdsReader.ino file in the Arduino IDE.

4. Add Required Libraries:

   Install the necessary libraries in the Arduino IDE: OneWire library DallasTemperature library LiquidCrystal_I2C library Go to Tools > Manage Libraries and search for these libraries to install them.

5. Select the Correct Board and Port:

   Go to Tools > Board and select the appropriate board (e.g., Arduino Uno, Nano, etc.). Go to Tools > Port and select the correct COM port for your connected Arduino.

6. Upload the Code:

   Click the Upload button in the Arduino IDE to upload the code to your board.

Formulae Used

1. Temperature Coefficient:
   T.C. = 1.0 + 0.02 * (Twater - 25.0)

2. Electrical Conductivity (EC):
   EC = (rawEC / (T.C)) * EC_Calibration

3. Total Dissolved Solids (TDS):
   TDS = (133.42 * EC^3 - 255.86 * EC^2 + 857.39 * EC) * 0.5

Example Output

The system displays the TDS, EC, and temperature values on the LCD as shown below: TDS EC Temp 333 0.53 25.44

Applications

• Water Quality Monitoring: Suitable for aquariums, hydroponics, and household water analysis.
• Sustainable Water Management: Helps ensure safe and healthy water usage.

Conclusion

This simple and affordable water quality monitoring system provides real-time insights into water contamination levels, empowering users to make informed decisions about water consumption.
