DFROBOT RS485 MODBUS-RTU Soil NPK Measurement Sensor

Soil Sensor, designed to measure and monitor nitrogen (N), phosphorus (P), and potassium (K) levels in the soil , optimizes soil fertility and creates ideal conditions for plant growth. It features a wide voltage power supply range of 5-30V and reliable data output through the RS485 MODBUS-RTU protocol. It is compatible with Arduino UNO and TTL - RS485 expansion board for easy installation. The ability to measure nitrogen, phosphorus, and potassium helps optimize soil Show More
