School Savers - Vernier SMS-BTA Soil Moisture Sensor

Vernier SMS-BTA Soil Moisture Sensor

The Soil Moisture Sensor uses capacitance to measure the water content of soil (by measuring the dielectric permittivity of the soil, which is a function of the water content). Simply insert this rugged sensor into the soil to be tested, and the volumetric water content of the soil is reported in percent.

Specifications
Range: 0 to 45% volumetric water content in soil (capable of 0 to 100% VWC with alternate calibration)
Accuracy: ±4% typical
Resolution: 0.1%
(LabQuest 2, LabQuest, LabQuest Mini, Go!Link, LabPro)
Power: 3 mA @ 5VDC
Operating temperature: –40°C to +60°C
Dimensions: 8.9 cm × 1.8 cm × 0.7 cm (active sensor length 5 cm)
