Soil Moisture Sensors

FarmSolutions irrigation management

Soil Moisture sensing technology has been around for several decades and is a widely accepted technology worldwide. Several growers using these tools still regularly check their soil moisture readings manually, which can easily consume time and resources when driving to each sensing location. Using the FarmSolutions system, growers have constant access to current soil moisture conditions with readings being taken every 15 minutes. Soil Moisture probes are configured to grower preference and can include custom sensing depths, soil temperature, EC readings, and salinity measurements.

FarmSolutions has a whole new approach to soil moisture monitoring, we know that a one size fits all approach is not perfect, so we incorporate a variety of soil monitor options. Irrometer, Decagon, Sentek, AquaCheck, and HSTI brands are used in FarmSolutions to create a tailored sensor package that fits your individual needs. Whether you need a single depth sensor or a multi-depth sensor with EC monitoring we have you covered.

Available Sensor Options

FarmSolutions works with a variety of soil moisture sensors

We proudly integrate with the leading manufacturers in soil moisture monitoring, localized weather stations, and irrigation control, allowing growers to simply plug and play with hardware components of their choice. Several probe varieties are available allowing customization for basic or more advanced functionality.

WaterMark Sensor

Irrometer Watermark 200 SS

The irrometer watermark sensor is a solid - state electrical resistance sensing device that is used to measure soil water tension, the sensor consists of a pair of highly corrosion resistant electrodes that are embedded within a granular matrix, it is designed to be a permanent sensor, placed in the soil to be monitored and “read” as often as necessary with a portable or stationary device.

    Sensor Features
  • Range of measurement from 0 to 239 cb (kPa)
  • Fully solid-state
  • Not affected by freezing temperatures
  • Internally compensated for commonly found salinity levels
  • NO maintenance required
Decagon 5TE Sensor

Decagon 5TE Sensor

The Decagon sensor is designed to measure the water content, electrical conductivity, and temperature of soil. It uses an oscillator running at 70 MHz to measure the dielectric permittivity of soil to determine the water content. A thermistor in thermal contact with the sensor prongs provides the soil temperature, while the screws on the surface of the sensor form a two-sensor electrical array to measure electrical conductivity.

    Sensor Features
  • Measures salt levels through bulk electrical conductivity.
  • Makes all three measurements (volumetric Water content, temperature and EC) independently
  • Steel screws make the 5TE a more robust sensor.
  • Utilizes a five point dielectric calibration to provide more accurate dielectric permittivity measurements.
  • Uses a 70MHz frequency, which minimizes salinity and textural effects, making it accurate in most soils.
Sentek EasyAG

Sentek EasyAG

The EasyAG is a slim- line, easy to install probe, Available in two fixed lengths of 12in and 20in, the probes can be configured, they are ideally suited to shallow rooted crops or where it is only necessary to measure no deeper than 50cm.

    Sensor Features
  • Multiple sensors at fixed depths.
  • Sensors at: 4in (10 cm) , 8in (20 cm) , 12in (30 cm) , 15in (40 cm) , 20in (50 cm).
  • Probes are encased in customized access tubes
  • Protection of sensors by avoiding direct soil contact.
  • Specific sealing to ensure long-term operation

Sentek EnviroSCAN

The EnviroSCAN provides soil-water content profiles for irrigation scheduling or other water movement systems, with great flexibility for precision monitoring of water and salinity at multiple depths in a soil profile. The EnviroSCAN can monitor to depths up to 130 feet, using the same profiling probe. EnviroSCAN is customized for individual applications by adding sensors at user-specified measurement depths

    Sensor Features
  • Multiple Sensors with adjustable depth placement ( at 4 in increments).
  • Monitoring from Shallow depths 0 - 4in to deep installations up to 131 ft ( 40 meters).
  • Flexible probe lengths which can be customized to suit the application.
  • Up to 16 sensors on one probe ( moisture or moisture/ salinity)
  • Soil specific calibrations can be applied to individual sensors.

Sentek Drill & Drop

The Drill & Drop is a fully encapsulated, easy to install, soil measurement probe. Probes are available in two lengths, 60cm (24”) and 120cm (48”), with sensors fixed at every 10cm (4”) increment. Available with moisture, temperature and salinity sensors at every 10cm depth. It is ideally suited to situations where a monitoring probe may need to be moved between sites in short term and annual crops.

    Sensor Features
  • Fully encapsulated electronics
  • Tapered shape allows for extremely fast and high-quality undisturbed installation in majority of soil types
  • Ability to measure the true soil profile, NOT slurry increasing the reliability of soil moisture and salinity readings
  • Buriable to any depth
  • Less prone to machinery damage with electronics being completely buried

AquaCheck Classic Probe

The AquaCheck Classic soil moisture probe offers capacitance based soil moisture measurement offering up to six depths or sensors per probe. It requires an external logger or remote transmission unit and external power supply

    Sensor Features
  • A capacitance based continuous logging probe.
  • Probe lengths from 400mm to 1200mm.
  • Up to 6 soil moisture and 6 soil temperature sensors depending on the probe length.
  • Shaft diameter: 32mm.
  • Communication Interface options: Analog, SDI-12 (serial data interface, 1200bd), MODBUS, 2400bd
  • Compliance: CE certified.


HydraSCOUT Probe uses capacitance as the measuring technology, it can be deployed on all irrigation systems such as: Centre pivots, micro irrigation, drip irrigation, flood / surface irrigation.

    Sensor Features
  • Well suited for crops where a sub-surface probe is preferred.
  • It comes standard 5 sensors (up to 10).
  • Probe diameter is 38mm.
  • Probe lengths options are from 100 mm (4in) to 1,500 mm. (60in)
