746 746  NSPH01 is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at [[this link>>url:https://www.dragino.com/downloads/downloads/LoRa_End_Node/LSE01/Calibrate_to_other_Soil_20220605.pdf]].
