Frequently Asked Questions

What is the wiring and communication protocol for the RS485 interface?

The RS485 interface uses a standard 2-wire (A/B) connection and communicates via the Modbus-RTU protocol. You will need a USB-to-RS485 converter or an RS485-capable PLC to read the data. The device address and register map for moisture, temperature, and EC readings are detailed in the product datasheet.

Can I power this sensor with a 12V battery in the field, and how do I select the output type?

Yes, the 4.5-30V DC input range fully supports 12V battery or solar power systems. The output type (RS485, 4-20mA, or 0-10V) is typically configured via internal DIP switches or by ordering a specific model variant. Consult the manufacturer's documentation for the configuration procedure of your unit.

Is the probe suitable for permanent burial, and how does the IP68 rating hold up?

Yes, the 316L stainless steel construction and IP68 rating make it designed for permanent installation directly in soil. The IP68 rating ensures complete protection against prolonged immersion in water and dust ingress, guaranteeing reliable operation in saturated or flooded conditions.

How do I calibrate the sensor for different soil types?

The sensor comes pre-calibrated for general mineral soils. For high-accuracy requirements in specific substrates (e.g., peat, clay, or soilless media), a soil-specific calibration may be necessary. This involves taking sensor readings in samples of known moisture content (via gravimetric method) and applying a linear correction factor to the output.
