Get a complete picture of what's happening below the surface. This wireless soil monitoring solution measures moisture, temperature, and electrical conductivity simultaneously — giving Growlink users the data they need to optimize irrigation schedules, prevent over- and under-watering, and make informed fertigation decisions. Stainless steel probes with built-in temperature compensation deliver reliable readings season after season, even when buried continuously in the soil.

What This Sensor Monitors

Soil Moisture

Volumetric water content from 0–100% m³/m³ with ±2% accuracy in the critical 0–50% range. Know precisely when and how much to irrigate.

Soil Temperature

–30°C to +70°C range at ±0.5°C accuracy with built-in temperature compensation — essential for root-zone management and germination timing.

Electrical Conductivity (EC)

0–10 mS/cm range at ±3% FS accuracy. Monitor nutrient concentration levels in the root zone to fine-tune fertigation programs.

Sensor Specifications

Parameter	Range	Accuracy
Soil Moisture	0–100% (m³/m³)	±2% (0–50%) / ±3% (51–100%)
Soil Temperature	–30 to +70°C	±0.5°C
Electrical Conductivity	0–10 mS/cm	±3% FS

Key Features

Long-Range Wireless

LoRaWAN® 863–930 MHz transmits from deep in the field or greenhouse without Wi-Fi infrastructure. Optional NB-IoT for cellular-only sites.

Multi-Depth Profiling

Deploy multiple probes at different soil depths on a single hub using splitter cables — monitor the full root-zone profile from one device.

IP68 Rated Probe

Fully submersible and sealed for permanent in-ground installation. Stainless steel construction resists corrosion from fertilizers and salts.

Temperature Compensation

Built-in compensation corrects EC and moisture readings for soil temperature variation, ensuring accuracy across seasons and climates.

Flexible Power

Powered via included DC supply (12 VDC). Optional solar panel add-on for off-grid field deployments far from power infrastructure.

Growlink OS Integration

Soil data feeds directly into Growlink irrigation and fertigation automation — trigger zone-level responses based on real root-zone conditions.

What's in the Box

1× Sensor Hub

1× Sensor Probe IO

1× Soil Sensor (stainless steel probes)

1× Power Supply for Sensor Hub

1× SensorHub Wall Mount

1× Pole Mount for SensorHub (φ65–89 mm)

Power Requirement: The Sensor Hub with Sensor Probe IO and connected soil sensor cannot be powered by batteries. The included DC power supply must be used, or an optional solar panel add-on for off-grid sites. LoRaWAN and NB-IoT variants are available — NB-IoT supports CAT M1 (higher data rates) and CAT NB2 (ultra-low power, extended coverage).
