Introduction
The PASCO Model PS-2163 Soil Moisture Sensor works with a PASCO interface to collect soil moisture
data. The sensor consists of the Soil Moisture Sensor box and the Soil Moisture Probe (cable
assembly).
The sensor measures volumetric water content (VWC) percentage of a soil sample. Volumetric water
content is the volume of soil water per unit of total volume. In simple terms, dry soil consists of solid
