IoT Driven Water Intelligence System

Abstract

Water is one of the most valuable natural resources, and maintaining its quality is essential for both human health and environmental balance. Conventional water testing methods are mostly manual, time-consuming, and cannot provide real-time updates. To overcome these limitations, this paper proposes an IoT Driven Water Intelligence System that continuously monitors and controls water quality using smart sensors and an embedded microcontroller. The system utilizes pH, TDS, turbidity, and temperature sensors to collect data, which is processed by an ESP32 microcontroller and displayed on an OLED screen. The collected readings can also be sent wirelessly to a cloud dashboard for online observation. When unsafe water parameters are detected, the system automatically activates a relay-based purification control unit to improve water quality. This intelligent and low-cost IoT model ensures real-time monitoring, faster response, and efficient purification control, making it suitable for domestic, industrial, and environmental applications.
