Soil NPK-S (RS485 type) sensor

Soil parameters measuring

Nitrogen Phosphorus Potassium : Measuring range: 1-1999 mg/kg(mg/L)
                                                             Resolution:1 mg/kg(mg/L)
                                                             Response time: <1S

Reminder
The measurement of NPK adopts the general rapid detection method, so there are certain errors, Use with caution for planting reference.
However, the sensor supports the function of writing NPK data. You can use standard instruments to measure NPK then write in to provide data for monitoring system.
