But the sensor supports the function of writing NPK data. You can measure nitrogen, phosphorus and potassium using standard instruments and write them to provide data for your monitoring system.
RS485 Modbus soil sensor 7 in 1 measures soil moisture temperature humidity EC PH NPK
It measures soil temperature, moisture, PH, electrical conductivity (EC), etc. It is suitable for various soils due to the small soil salt content. Buried in soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, and completely waterproof.
