| Summary: | Hydroponic systems rely on healthy root growth for efficient nutrient absorption, but prolonged submersion in contaminated water can lead to plant death. This project proposes the development of a smart IoT-based hydroponic plant water level system to monitor water flow in a hydroponic tank, ensuring optimal aeration for healthy root systems. In addition to enhancing root development, this project also enhances user convenience and minimizes manpower effort. This project employs a NodeMCU Wi-Fi module (ESP8266) to connect to a cloud platform, integrating TDS and ultrasonic sensors for monitoring nutrient levels and root growth in hydroponic systems, using the Arduino IDE for software compilation and the Blynk platform for monitoring. Crucially, the system automatically controls water pumps based on sensor data. When the TDS sensor detects nutrient levels below a set threshold or the ultrasonic sensor indicates insufficient water depth, the corresponding water pump is activated to maintain optimal conditions. This system presents a comprehensive solution for maintaining ideal hydroponic conditions, fostering healthier crops and sustainable farming practices. © 2024 IEEE.
