Soil Moisture Sensor

Specification: A soil moisture sensor is an electronic instrument used to measure the volumetric water content within soil profiles. In a laboratory or greenhouse setting, it is essential for precision irrigation control, hydrology studies, and monitoring plant physiological stress in controlled environments.

Technical Specifications:
* Measurement Principle: Frequency Domain Reflectometry (FDR) or Capacitance
* Measurement Range: 0 to 100% Volumetric Water Content (VWC)
* Accuracy: ± 2% to ± 3% VWC (with site-specific calibration)
* Output Signal: Analog (0–5V), SDI-12, or RS-485 Modbus
* Operating Temperature: -40°C to +60°C
* Power Consumption: 3–15 mA during measurement
* Probe Length: 5 cm to 20 cm
* Enclosure Rating: IP68 (Watertight/Submersible)
* Soil Temperature Measurement: Integrated thermistor (optional)
