HOBO by Onset T-DEC-10HS - 10HS Soil Moisture Sensor
The soil moisture sensor measures the volumetric water content (VWC) of soil using stainless‐steel needles. A ferrite core positioned on the sensor cable 7.6 cm (3 inches) away from the sensor head is used to isolate the sensor from any interferences in the system. This mitigates any potential noise from the system on the measured sensor data.
