Soil moisture sensor

Soil moisture sensors measure values from –200 kPa to 0 kPa and are factory-calibrated, so no initial calibration is needed. Over time, accuracy may drift and recalibration may become necessary. To recalibrate, fully submerge the probe in water; if the reading differs from 0 kPa, adjust the Measurement Offset parameter so that the displayed value is exactly 0 kPa.

Important! Proper installation of the soil moisture sensor is essential for accurate measurements. Always follow the provided installation instructions carefully.

Measurement Offset	Adds or subtracts an offset value to the pressure measurement result in kilopascals (kPa).	Range: -100 to 100 kPa.

A fully wet soil moisture probe should display 0 kPa. A completely dry probe should display –200 kPa, though full drying may take up to 24 hours.
