IoT Based Soilless Cultivation

An inventive technique for growing plants without soil is IoT-based soilless agriculture, which uses nutrient-rich water to increase growth efficiency.This research introduces an Internet of Things-based automated soilless farming system that maximizes plant health by combining automated control and real-time monitoring.The system makes use of Node MCU for cloud-based data transmission to Thing Speak, allowing for remote monitoring and control, and Arduino for local processing.Optimal growing conditions are ensured by key sensors, such as an ultrasonic sensor for water level detection, a pH sensor for nutrient level monitoring, a DHT11 for tracking temperature and humidity, and an LDR for measuring light intensity.Water circulation and nutrient delivery are automated by two water pumps.While a CPU fan guarantees adequate air circulation and LEDs provide artificial lighting.Relays use sensor data to regulate the lighting and pumps.By automating tasks like lighting controls, water refills, and nutrient distribution, the system minimizes human involvement and maximizes resource use.Users can remotely monitor and adjust environmental conditions using real-time sensor data posted to Thing Speak, increasing the sustainability and efficiency of soilless farming.Crop productivity is increased, resources are saved, and precision agriculture is supported by an Internet of Things-based system.
