Feature:1. The protection grade is IP68, which can be buried in the soil for a long time, resistant to long‑term electrolysis, corrosion, vacuum filling and sealing, completely waterproof.2. The soil moisture temperature humidity sensor is suitable for the measurement of soil temperature and moisture, with high precision, quick response and stable output.3. This soil moisture sensor is less affected by soil salt content, and is suitable for all kinds of soil.4. Analog output is adopted, which is flexible and can output current type or voltage type. Three wire system can be used for wiring.5. It is widely used in scientific experiments, water‑saving irrigation, greenhouse, flowers and vegetables, grassland and pasture, soil rapid measurement, plant culture, sewage treatment, grain storage and measurement of moisture content and temperature of various particles.Specification:Condition: Brand NewItem Type: Soil Moisture SensorMaterial: ABS, 316 Stainless SteelPower Supply: 12-24V DCMoisture Measurement Range: 0-100%Storage Environment: -40℃ to -80℃Moisture Accuracy: ± 3% (In Range of 0 - 53% ) / ± 5% (In Range of 53 - 100%)Response Time: <1sTemperature Measurement Range: -40℃ to -80℃Temperature Accuracy: ±0.5 ℃Installation Method: All buried or all probes inserted into the measured mediumProtection Level: IP68Voltage Output Type: 0-10VVoltage Output Load: ≤250ΩPower Consumption: <0.15WWorking Pressure Range: 0.9-1.1atmWeight: Approx. 197g / 6.9ozSize:Length: Approx. 13.8cm / 5.4inThickness: Approx. 1.5cm / 0.6inWiring:Cable ColorDescriptionPower SupplyBrownPower Supply Positive (12-24V DC)BlackPower Supply Negative CommunicationWhite HumidityVoltage / Current Output is PositiveGray TemperatureVoltage / Current Output is PositiveBlueNCYellowNC.Package List:1 x Soil Moisture Sensor1 x Instruction ManualNote:1.Please allow 0-1 inch error due to manual measurement.
