Product information "DFRobot RS485 NPK soil nutrient sensor, nitrogen, phosphorus, potassium, for Arduino, IP68, 5-30V"

MODBUS-RTU RS485 Soil NPK measuring sensor (IP68, 5-30V)
The soil NPK measuring sensor is a state-of-the-art device that provides fast and precise data on nitrogen, phosphorus and potassium levels in the soil. This information is crucial for optimising soil fertility and creating ideal conditions for plant growth. With a wide voltage range of 5-30V and data output via RS485 using the reliable MODBUS-RTU protocol, the sensor offers fast response times and a stable, reliable output. The sensor is compatible with Arduino UNO R3 and TTL to 485 expansion board, allowing quick setup of the test environment.
