PH sensor using Fuzzy Logic on Arduino for the monitoring and control of acidity or alkalinity in reservoir's irrigation water

This present paper introduces an innovative approach to automatically monitor and control acidity or alkalinity in irrigation water. The system effectively calculated the amount of acidic or alkaline solution that had to be added to the reservoir using fuzzy logic techniques programmed into the Arduino Mega. Our control rules were meant to maintain a PH of around 5 to 6.4 (Acidic) in the irrigation water stored in the reservoir. The correct PH for optimal plant root development is around 5 to 6.4. Current methods of PH control are manual, hence this paper proposes a novel way of controlling PH automatically for optimal plant root development.
