Features1Product Composition: Soil moisture sensor is composed of a power supply module, a transmission module, a zero drift and temperature compensation module, and a data processing module. 2Powerful Function: The sensor has built in signal sampling and amplification, zero drift and temperature compensation functions, which have little impact on soil quality and are widely used in a wide range of areas. 30?100% Measurement Range: High measurement accuracy, reliable performance, quick response, good interchangeability, and high data transmission efficiency. 4Compact Design: This soil moisture sensor has a small and light appearance, which is easy to carry and connect. The cable length is about 1.5 meters, which can meet the needs of use. 5Long Lasting Use: Supports dielectric constant signal output, good sealing, IP68 protection level, can be directly buried in soil and used, not easy to be corroded or rusted.SpecificationItem Type: Soil Moisture SensorMaterial: ABSWeight: Approx. 141g / 5ozProbe Material: Stainless SteelSealing Material: Epoxy ResinMeasurement Parameter: Soil Volumetric Water ContentMeasuring Range: 0-100%Measurement Accuracy: 3%Resolution: 0.1%Measurement Area: A cylinder with a diameter of 7cm and a height of 7cm surrounding the central probe with the central probe as the centerProbe Diameter: Approx. 3mm / 0.12inResponse Time: 2sCable Length: Approx. 1.5m / 4.9ftWorking and Storage Conditions:Working Temperature: -40-85Working Humidity: 0-100%RHStorage Temperature: -40-125Storage Humidity:
