EDO STATE UNIVERSITY IYAMHO DESIGN AND IMPLEMENTATION OF WATER QUALITY MONITORING SYSTEM
Abstract
This project presents the design and implementation of an IOT-based smart Water Quality Monitoring System
aimed at providing an efficient, cost-effective, and scalable solution for continuous water quality assessment.
The system integrates various sensors to measure key parameters such as pH, temperature, turbidity, Total
Dissolved Solids (TDS) sensor and electrical conductivity (EC). These sensors are interfaced with an ESP32
microcontroller unit, which processes the data and transmits it wirelessly to the Blynk cloud platform via Wi-
Fi for remote monitoring. A 16x2 LCD, status LEDs, and an alarm buzzer provide immediate local feedback
on water safety. The device operates on a 5V DC power supply converted from 220V AC mains, and all
components are housed in a protective pattress box. It is developed to provide real-time alerts and historical
trends, enabling authorities and stakeholders to make informed decisions. The system was tested using ten
different sources of water. The result show that out of this ten, four were acidic and three showed a high value
of alkalinity, and three were suitable for drinking. The results I obtained after testing multiple water sources
showed clear distinctions between safe and unsafe water sources, highlighting its effectiveness in real-time
environmental monitoring. The solution is low-cost, scalable, and suitable for various applications, including household
use, agriculture, and water treatment facilities.
