The Soil Nutrient Tester NPK Sensor is an advanced digital soil analysis device designed to measure essential soil nutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—directly in the field. Built with a rugged IP68-rated stainless-steel probe, this sensor enables farmers, agronomists, researchers, and greenhouse operators to monitor soil fertility in real time and make informed fertilizer management decisions. The sensor supports RS485 Modbus communication for seamless integration with IoT platforms, weather stations, and smart agriculture systems.
