Water quality monitoring is essential to ensure safe drinking water and to protect public health. This project presents an IoT-based cloud water quality monitoring system that continuously measures important water parameters uses ESP32 as the main controller to collect and process data from multiple sensors. The system includes a DS18B20 Temperature Sensor for temperature measurement, a pH sensor to detect acidity or alkalinity of water, a turbidity sensor to measure water clarity, and a TDS sensor to determine the total dissolved solids present in the water. All sensor data are read and processed by the ESP32 microcontroller which has an inbuilt Wi-Fi. Using the built-in Wi-Fi capability of ESP32, the measured parameters are uploaded to the cloud platform ThingSpeak for real-time monitoring and data storage. This IoT-based monitoring system helps in early detection of water contamination and enables remote monitoring through the cloud. The proposed system is low-cost, efficient, and suitable for applications such as drinking water monitoring, industrial water quality checking, and environmental water analysis.    

The main objectives of the project are:

  To design and develop an IoT-based water quality monitoring system using the ESP32 for real-time data processing and communication.

  To measure important water quality parameters such as temperature, pH level, turbidity, and total dissolved solids (TDS) using sensors like the DS18B20 Temperature Sensor, pH sensor, turbidity sensor, and TDS sensor.

  To upload and store water quality data in the cloud using the IoT platform ThingSpeak for remote monitoring and analysis.

  To develop a low-cost, efficient, and continuous monitoring system that can be used in drinking water systems, industries, and environmental water monitoring applications.
