Select the output and install the rods without disturbing the soil contact
Range, wiring and installation method affect whether readings can be compared over time.
- Choose a 0-50% or 0-100% moisture range and a 0-5000, 0-10000 or 0-20000 µS/cm EC range before release.
- Choose one output: 0-2 V, RS485 Modbus RTU or SDI-12. These are ordered alternatives, not simultaneous standard outputs.
- The measurement-temperature range is -30 to +70 °C. The separate -40 to +80 °C value is the operating-environment limit.

How to choose
- Define the root-zone depths and number of sensing points that affect irrigation or crop decisions; one point rarely represents a whole field.
- Select a 0-50% or 0-100% moisture range and a 0-5000, 0-10000 or 0-20000 µS/cm EC range.
- Choose one output: 0-2 V, RS485 Modbus RTU or SDI-12. Match its supply, cable and receiving logger or RTU.
- Install the three rods in close contact with undisturbed soil, avoid stones and do not rock the probe after insertion.

Applications
This three-rod probe measures soil moisture, soil temperature and an in-situ electrical-conductivity signal at one sensing point. Moisture uses the FDR method and EC uses AC excitation. Select one moisture range, one EC range and one output before quotation. The field EC reading is useful for trends and comparisons under a defined soil and moisture condition; it is not, by itself, a laboratory soil-salinity result.
- Irrigation scheduling based on moisture trends at defined root-zone depths
- Greenhouse, orchard and field trials that compare multiple sensing points
- Seasonal soil moisture, temperature and EC trend monitoring
- Buried monitoring installations with a planned inspection and comparison-reading procedure
What to include in your quote request
- Root-zone depths, number and layout of sensing points
- Soil type, expected moisture range and EC comparison objective
- Selected moisture range, EC range and 0-2 V / RS485 / SDI-12 output
- Logger or RTU input, device addressing, sampling interval, cable length and supply
- Surface or buried installation method, comparison-reading plan, quantity and project stage

Frequently asked questions
Which output should be selected for this soil sensor?
Use RS485 Modbus RTU for a digital multi-drop field bus, SDI-12 for a compatible environmental logger, or 0-2 V for a short analog signal path. Only one output is selected for the ordered configuration.
What are the measurement and operating temperature ranges?
The reviewed soil-temperature measurement range is -30 to +70 °C with ±0.5 °C accuracy and 0.1 °C resolution. The separate -40 to +80 °C value describes the operating environment, not the measurement range.
How should the three rods be installed?
Insert them into undisturbed soil with close contact on all sides, avoid stones and do not rock the probe. Use vertical insertion from the surface or horizontal insertion into a prepared pit wall, then document depth and orientation for repeatable comparisons.
Can the EC reading be used as a laboratory soil-salinity result?
No. It is an in-situ conductivity signal that changes with soil type, moisture, temperature and installation. It supports field trends and comparisons when the method is controlled; certified salinity results require the appropriate laboratory procedure.
How is this sensor connected to a remote monitoring system?
Connect the selected sensor output to a compatible logger or RTU, then use the RTU or gateway for 4G, Ethernet or another uplink. The register map, device address, analog scaling, cable, power and reporting interval are checked as one signal chain.
What should I provide when requesting a quote for the Soil Moisture, Temperature & EC Sensor?
Root-zone depths, number and layout of sensing points; Soil type, expected moisture range and EC comparison objective; Selected moisture range, EC range and 0-2 V / RS485 / SDI-12 output; Logger or RTU input, device addressing, sampling interval, cable length and supply
Where can I compare available model options?
Open the Agriculture & Weather Hardware Catalog linked on this page. It lists audited SG-coded selections; the ordered configuration is confirmed in the quotation.
Will it work with my existing system?
Compatibility is reviewed against your field signals, protocols and upstream platform. Typical pairings include RS485 Modbus RTU masters using the reviewed register map and selected device address, SDI-12 data loggers using the matching ordered interface, 0-2 V analog inputs with a compatible supply and common signal ground.
