SOIL NPK SENSOR RS485 SNPK

Description

The Soil NPK Sensor RS485 is a high-precision digital sensor designed to measure the Nitrogen (N), Phosphorus (P), and Potassium (K) content in soil, enabling efficient monitoring of soil fertility. With RS485 communication protocol, it ensures long-distance and stable data transmission, making it ideal for smart agriculture, greenhouse farming, precision irrigation, and soil research projects.
