图片1

1.Triple-Parameter Precision

Measures soil moisture (0–100%), temperature (-40°C to 80°C), with high accuracy (±3% moisture, ±0.5°C temperature).

Flexible output: RS485 (Modbus-RTU) or analog voltage (0–2V) for seamless integration into diverse systems.

2.Rugged & Weatherproof Design

IP68 waterproof rating allows direct burial in soil, ideal for harsh environments (-40°C to 80°C).

Epoxy-sealed body and stainless steel rods ensure long-term durability and corrosion resistance.

3.Smart Farming Ready

Modbus-RTU protocol enables easy integration with IoT platforms and agricultural automation systems.

4.Low Power & Energy Efficiency

Reverse power protection and Built-in TVS/ESD protection.

5.User-Friendly Installation

Sharp, durable rods for effortless insertion into soil (surface or buried).

Pre-loaded calibration formulas for VWC, EC, and salinity across soil types (mineral, sand, clay, organic).

◀◀  Application Scenarios  ▶▶


◆◆ Applications:  

  • Precision Agriculture: Optimize irrigation and fertilization based on real-time soil data.

  • Greenhouse Management: Monitor microclimates to boost crop yields.

  • Environmental Research: Track soil health and salinity in ecological studies.

  • Smart Irrigation Systems: Automate water usage to reduce waste.

  • Urban Farming: Ensure optimal growing conditions in controlled environments.


◆◆ Surface installation

  • Clear away any stones. Pre-form holes in very hard soils before insertion.

  • Push the sensor into the soil until the rods are fully inserted. Ensure good soil contact.

  • If you feel strong resistance when inserting the sensor, you have probably hit a stone. Stop, and re-insert at a new location.

Note: The sensor is suitable for soil surface temperature measurements.


◆◆ Installing at depth

  • Make a 45mm diameter hole, preferably at about 10° to the vertical using a auger.

  • Push the sensor into the soil until rods are fully inserted. Ensure good soil contact.

  • Fill and repack the hole with soil.


◆◆ Alternatively

Dig a trench, and install horizontally.
