GAIA – the IoT soil monitoring system for smart agriculture
GAIA measures soil temperature, temperature-compensated water content, and electrical conductivity—maintenance-free, PV-powered, and wireless via LoRaWAN®, mioty®, NB-IoT, or LTE-M.
Soil data that really tells you something
GAIA combines soil moisture, temperature, and conductivity measurement in a maintenance-free IoT system.
Soil temperature
Precise measurement of internal soil temperature (-20 °C to +60 °C, ±1 °C).
Soil moisture
Temperature-compensated measurement of soil moisture (0–60%, ±3%).
Electrical Conductivity
Measures bulk and pore EC—an ideal indicator of fertilizer concentration.
PV-powered
Maintenance-free operation thanks to a rechargeable battery and integrated solar module.
NFC-configurable
Contactless commissioning and parameterization via NFC – no tools required.
IP67 industrial housing
Resistant to dust, water, and dirt—even in harsh environmental conditions.
Plug & Play
Industrial connections, up to 3 sensors per box – quick and clean installation.
Multi-connectivity
LoRaWAN®, mioty®, NB-IoT, or LTE-M – suitable for any wireless infrastructure.
Bulk EC isn’t enough— pore EC is the key
Other soil sensors typically measure only total electrical conductivity (bulk EC), which is influenced by water volume and ions. GAIA additionally measures pore EC—a much more precise indicator of actual fertilizer concentration.
Why smart soil monitoring?
Those who understand the soil can manage it effectively. GAIA provides the data foundation for efficiency, sustainability, and higher yields.
Precise fertilizer content
GAIA precisely measures the fertilizer content in the soil – optimally adjust to the plants’ nutrient requirements.
Moisture & Temperature
Continuous measurement of soil moisture and temperature – targeted irrigation and care.
Efficient use of resources
Targeted measurements save water and fertilizer – less waste, more sustainability.
Autonomous system
Rechargeable battery + solar panel – long service life with no maintenance.
No calibration required
High-precision, temperature-compensated measurements, factory-calibrated.
Rugged and durable
Industrial-grade housing and connectors for harsh outdoor environments.
From Farm Fields to Smart Cities
GAIA is suitable wherever soil parameters matter—from agriculture to infrastructure.
Agriculture
Field crop cultivation, fruit and vegetable plantations, gardens, and greenhouses.
Environment & Nature Conservation
Monitoring of protected areas and nature reserves.
Smart City
Urban green spaces, parks, and green areas in urban areas.
Construction
Soil analysis prior to construction projects and monitoring of soil moisture on construction sites.
Forestry
Large-scale monitoring of forest and woodland areas.
Infrastructure
Monitoring of soils around roads, bridges, tunnels, dams, and water reservoirs.
