HydroTech: Water Quality Monitoring System on Smart Agriculture

Agriculture is at the center of all economic activity since it is the link between agricultural expansion and economic riches. New and developing technology has the potential to constantly increase the productivity, profitability, and quality of our key agricultural systems. Hydroponics is a method of planting or producing plants that do not require soil and instead relies on water, nutrients, and oxygen. It requires accuracy, patience, and constant monitoring, all of which are difficult to do. The objective of this research is to create a monitoring tool for the automated flow of nutrients in hydroponic plants using an Arduino microcontroller and a smartphone. The HydroTech can detect sensor data from four parameters: temperature, pH, turbidity, and electrical conductivity, and simultaneously display its reading in an application. The device has an ESP32, which can transport data over WIFI and Bluetooth. Two weeks of lettuce testing revealed that the sensors and application worked well. The equipment was practical and useful since it met the specifications. The researcher suggests utilizing digital sensors because the device employs analog sensors and reading depends totally on the type of sensor used
