In the modern world, water pollution is a significant cause of various water-borne diseases, including dengue, cholera, and malaria, among others, affecting human beings. Approximately 40% of global deaths are attributed to water pollution. Therefore, it is crucial to continuously monitor the quality of drinking water during its distribution to consumers. This article proposes a cost-effective design and expansion of a real-time water quality measuring system using the Internet of Things (IoT). The system aims to measure physical and chemical parameters such as temperature, humidity, pH, and turbidity. Water contamination poses a significant threat to sustainable development. Continuous monitoring of water quality is essential to ensure the availability of safe drinking water. This paper presents the development and implementation of a simplified framework for real-time water quality monitoring using IoT. The system consists of multiple sensors capable of measuring various physical and chemical parameters of water, including temperature, pH, turbidity, and humidity. These sensor readings can be configured and monitored by a central controller, with the ATMEGA328 model serving as the core controller. The collected sensor data can be accessed online using a Wi-Fi network. The automation in the project is controlled by a microcontroller, which receives data transmitted from a PC over Wi-Fi through a Wi-Fi module. All components are interconnected with the Arduino microcontroller. The Arduino ATMEGA328 microcontroller processes the input and generates the necessary output using the ARDUINO IDE with Embedded C programming. The entire system is powered by a regulated power supply, providing a DC voltage of 5V to all hardware modules.
