Abstract
Modern agriculture demands precise management of soil nutrition to optimize crop yield and minimize resource wastage. This presents a smart agriculture solution that utilizes an NPK sensor to monitor and regulate the levels of essential nutrients - Nitrogen (N), Phosphorus (P), and Potassium (K) in soil. The system is designed to automatically adjust nutrient levels when they fall below optimal values. Integrating NPK sensors in agriculture soil nutrition management represents a significant advancement in precision farming. These sensors are designed to detect the levels of the essential nutrients in the soil accurately. When the nutrient levels fall below optimal thresholds, a signal is sent to open the corresponding solenoid valve, allowing for the precise application of Nitrogen, Phosphorus, and Potassium fertilizers. Solar panels are considered a clean energy source because they do not produce harmful emissions of greenhouse gases during electricity generation. They rely solely on sunlight, which is an abundant and renewable resource An LCD provides real-time information to farmers, offering insights into nutrient levels and helping them make informed decisions about fertilization.
