Soil NPK Sensor

₹3,500.00

Overview

The Soil NPK Sensor is an advanced agricultural sensing device designed to detect the nitrogen (N), phosphorus (P), and potassium (K) content in soil. By measuring these essential nutrients in real time, the sensor enables farmers, researchers, and automated irrigation system managers to evaluate soil fertility and optimize fertilizer usage efficiently.

Constructed with a rugged, waterproof casing and durable stainless steel probe prongs, this sensor is built for long-term insertion into soil or growth media. It provides real-time digital communication via RS485 MODBUS protocol, making it ideal for integration into smart agriculture systems, IoT gateways, and automated controllers.
