This paper illustrates contemporary agricultural methods where vegetation can thrive without soil, utilizing nutrient solutions. As we know, hydroponics and aeroponics are gaining popularity. IoT enables us to automate these systems thus reducing human intervention. The project’s main motto was to produce a hydroponic system which was entirely automated. The capability to streamline the setup from minimal inputs from human and maximize crop productivity—this research illustrates the application of ESP-32 microcontroller that includes a pH sensor, TDS sensor, 5 V submersible pump, and an OLED display. Although the TDS sensor maintains the NPK fertilizer suspended in the water, a pH sensor can identify various fluctuations in nutrient levels. pH and TDS results are employed in system to examine the condition of the crops. For investigation of the data, these values are additionally saved in the Arduino IDE. To maintain the water quality, the system utilizes an OLED module together with automated pumps. This setup provides practical and efficient hydroponic agriculture.
