7-in-1 RS485 Modbus Soil Sensor – NPK, pH, EC, Temperature, Humidity & Moisture Tester for Agriculture

Take the guesswork out of soil management with this advanced 7-in-1 Soil Sensor, designed for farmers, greenhouse operators, landscapers, researchers, and precision agriculture professionals. This intelligent digital sensor measures soil moisture, temperature, electrical conductivity (EC), pH, nitrogen (N), phosphorus (P), and potassium (K) simultaneously, providing real-time data for healthier crops and higher yields.

Built with a rugged IP68 waterproof design, this sensor features anti-corrosion alloy electrodes and durable flame-retardant epoxy sealing, making it ideal for long-term outdoor use in harsh environments. Whether you're managing a commercial farm, hydroponic system, greenhouse, garden, pasture, or irrigation project, this sensor delivers accurate and reliable readings you can trust.

The integrated RS485 Modbus communication protocol allows seamless connection to agricultural monitoring systems, IoT platforms, data loggers, PLCs, and automation equipment. With no chemical reagents required, the reusable probe offers fast response times, high precision measurements, and simple installation for continuous soil monitoring.
