AN IoT-ENABLED DESIGN FOR REAL-TIME WATER QUALITY MONITORING AND CONTROL OF GREENHOUSE IRRIGATION SYSTEMS

Abstract

Because hydroponic plant nutrients are dissolved in the water, water quality management is essential for growing healthy plants. Taking care of the total dissolved solids (TDS) and the pH (water acidity) is essential. The purpose of this research is to create an IoT-based water quality monitoring device. The average TDS after 30 days of automation with an Arduino UNO was 1162.82 ppm, and the gadget kicked on the nutrient pump whenever the TDS fell below 1000 ppm or the EC fell below 2. The mechanism self-adjusts the pH when it falls below 5.5 or rises above 6.5, with a mean of 6.17.
