Prototype NFT/DFT Hydroponic Data Collection Using IoT System

Hydroponic cultivation has several considerations that must be considered in terms of water treatment as the main source role for plant growth. With this problem, a monitoring system is needed that can monitor water conditions in DFT hydroponic irrigation pipes. The monitoring tool uses ESP32 which is the main role of the system that will read and send sensor data to support monitoring, where each sensor has its role. This system utilizes the MQTT protocol as a data communication medium. The test was carried out using the Prototyping research method. From the test results, it can be concluded that the monitoring tool has the ability to read several water conditions from the level of acidity or alkalinity, turbidity or water clarity, water temperature, water level and water flow rate or flow that is functioning properly and is displayed on the website page in real-time.
