Solar Powered Smart Water Monitoring System Based on IoT and Blynk Platform

This paper presents the solar powered smart water monitoring system using IoT. Water is an important and free natural resource that humans require on a regular basis. Maintaining water cleanliness is important and our shared duty. Most infections illnesses, which result in millions of deaths each year, are brought on by contaminated water. The purpose of this study is to analyze the water quality of Melor river in Kelantan and to develop a solar-powered Internet of Things (IoT) based water quality monitoring system. The device is powered by a solar array which deployed with three sensors that are turbidity, pH, and total dissolved solids sensors. The water’s parameter data has been sent to a data center in real time using an ESP32 microprocessor and sensors. Data on water quality can be monitored using a Blynk application on a smartphone through IoT development. The result presents the analysis which shows 34 hours for the battery to completely charge in a solar-powered system. The findings indicate that the neighborhood’s river’s water condition was suitable based on the water’s TDS content readings which is below 300 ppm. The pH measurement was good within the zone of 4-11 and the water was also identified as cloudy.
