Description

This soil sensor employs a resistive measurement principle via its three-pin probe to determine volumetric water content and environmental humidity. The integrated signal conditioning circuitry delivers stable, calibrated readings transmitted via an RS485 serial bus, supporting configurable baud rates (2400/4800/9600) for seamless integration into Modbus RTU networks.

Housed with an IP68 sealing grade, the sensor body and cable gland are protected against prolonged moisture ingress and dust. The probe’s anti-corrosion plating ensures consistent electrical contact and measurement accuracy across diverse soil chemistries, from agricultural fields to greenhouse substrates.

Key Features

  • Industrial-grade RS485 interface enables daisy-chaining and communication distances exceeding 1000 meters.
  • High-precision measurement with stability optimized for continuous soil fertility and irrigation monitoring.
  • Low-power design utilizing quality signal processing chips for sensitive and stable output.
  • Rugged, electrolysis-resistant probe construction for long-term deployment without performance degradation.
  • Wide compatibility with 12-24V DC power supplies common in automation and solar-powered field installations.
  • Portable design with a 2-meter integrated cable for convenient spot testing or permanent burial.

Applications

  • Precision irrigation control and water-saving management in smart agriculture and greenhouses.
  • Soil fertility and moisture content monitoring for crop research, horticulture, and turf management.
  • Environmental and meteorological station networks for climate and soil health data collection.
  • Long-term soil condition monitoring in vineyards, orchards, and botanical research facilities.
  • Integration into IoT-based farming platforms for automated soil data logging and analysis.

Frequently Asked Questions

What is the operating voltage range for this RS485 soil sensor?

The sensor operates on a 12 to 24V DC power supply. It is crucial to provide power within this range to ensure proper functionality of the internal circuitry and stable RS485 communication. Connecting a voltage outside this range may damage the sensor.

How do I communicate with this sensor and configure its baud rate?

The sensor uses a standard RS485 interface, typically implementing the Modbus RTU protocol. You will need an RS485-to-USB converter or a PLC with an RS485 port to connect it to a computer or controller. The baud rate is configurable and supports 2400, 4800, or 9600 bps; the specific configuration method (e.g., via internal DIP switches or Modbus commands) should be detailed in the sensor's dedicated datasheet.

Is the probe suitable for long-term burial in all soil types?

Yes, the 3-pin probe is constructed with corrosion-resistant, electrolysis-proof materials designed to withstand long-term exposure to acidic, alkaline, and saline soils. Combined with the IP68 waterproof rating of the sensor body and cable gland, the entire assembly is built for durable, permanent installation in harsh agricultural and environmental conditions.

What is the maximum cable length for reliable data transmission?

The sensor includes a fixed 2-meter cable. The RS485 standard itself supports much longer communication distances—up to 1200 meters—depending on baud rate and cable quality. For extensions, use shielded twisted-pair cable and proper termination to maintain signal integrity in noisy environments.
