It’s easy to understand soil moisture and temperature conditions with the IOT Plus Soil Moisture Sensor. Designed to improve irrigation scheduling and water-use efficiency, the sensor provides actionable data that helps determine when and where to water crops, plants, or landscaped areas.

Monitor Water Tension to Prevent Plant Stress

The IOT Plus Soil Moisture Sensor measures soil water tension (matric potential) and soil temperature. Using a resistive granular matrix sensing element, users can fine-tune tension thresholds to detect the earliest signs of water stress and irrigate before crops or plants are affected.

This unique sensing element delivers consistent, reliable calibration without requiring recalibration for each installation—saving time and ensuring repeatable results across deployments.

Integrated Temperature Measurement

The sensor also includes a thermistor-based temperature element, capable of measuring temperatures from –40°C to 125°C (–40°F to 257°F). These readings enable automatic temperature compensation of moisture measurements, eliminating the need to re-measure soil moisture when temperature conditions fluctuate.

Key Features

Additional benefits of the IOT Plus Soil Moisture Sensor include:

• Reliable performance in both extreme heat and freezing conditions

• Soil water tension measurement range of 0 to 240 centibar (cb) or kilopascal

• Corrosion-resistant, high-grade stainless steel construction

• Internal compensation for commonly occurring soil salinity levels

• Simpler installation and operation compared to traditional tensiometers

Smarter Irrigation Decisions

Deploy the IOT Plus Soil Moisture Sensor to reduce water waste, protect crops and landscaping from stress, and make data-driven irrigation decisions with confidence.
