Technical Description


Soil Temperature Moisture Salt Sensor provides continuous, stable and accurate measurement of the three most important soil parameters: moisture, salinity and temperature.


Usage Guidelines for Soil Temperature, Moisture & Salt Sensor


●  Installation                                                                                                                                                                               

Follow Instructions: Install strictly according to the provided manual.

Multi-Sensor Spacing: Maintain **>5 meters** between sensors when deploying multiple units.

Probe Handling: Wear protective gloves to avoid injury from sharp probes.

●  Operating Environment

Electromagnetic Safety:

    No high-voltage cables or strong magnetic fields within 5 meters.

    Avoid exposure to strong acids, alkalis, oils, or heavy metals.

Measurement Range: Ensure the environment stays within the sensor’s specified range (e.g., temperature, salinity).

Vibration-Free Zone: Install in stable locations with no strong vibrations.

●  Usage Restrictions

Purpose-Built Design: For soil measurement only—do not repurpose for liquids or other media.

Mechanical Protection:

    Avoid excessive force during installation.

    Never disassemble the sensor—unauthorized tampering voids the warranty.

●  Maintenance & Safety

Post-Installation Checks:

    Verify cable connections are secure.

    Calibrate periodically if used in extreme conditions.

Data Integrity: Monitor readings for anomalies caused by environmental interference.

Features


●  High-Precision Measurement

Delivers accurate soil data (moisture, temperature, salinity) when installed per guidelines, avoiding over-range or environmental interference.

●  Electromagnetic Interference Resistance

Designed to operate reliably in low-interference zones (no high-voltage cables or strong magnetic fields within 5 meters).

●  Durable Construction

Stainless steel probes resist corrosion and mechanical stress, suitable for long-term soil monitoring.

●  Multi-Sensor Scalability

Supports synchronized deployment of multiple sensors (spacing >5 meters) for large-area agricultural or environmental studies.

  • What’s the critical rule for installing multiple sensors?

    • ​Maintain >5-meter spacing​ between units. ⚠️ Closer spacing causes electromagnetic interference, significantly compromising accuracy.
  • Where should this sensor NEVER be installed?

    • Avoid locations with: ✘ ​High-voltage cables​ or motors (within 5m) ✘ ​Strong acids/alkalis​ (e.g., fertilizer spills) ✘ ​Constant vibration​ (near machinery) ✓ Ideal: Stable soil zones free of metal contaminants.
