Data Instead of Gut Feeling.

Traditional agriculture is based on experience - Smart Agriculture on facts. We replace the 'watering can principle' with precise data points to efficiently use fertilizer, water and energy.

Scheduled Irrigation

Irrigation on schedule wastes water or leads to waterlogging.

Precise Soil Moisture Measurement

Precise soil moisture measurement at various depths. Irrigation only when the plant needs it.

Wrong Climate Promotes Fungal Growth

Excessive humidity promotes fungal infections like Botrytis or powdery mildew.

VPD Monitoring

We monitor the ratio of temperature to humidity (Vapor Pressure Deficit) and warn before the climate tips.

No WiFi, No Power

Greenhouses and fields are often far apart. No WiFi, no power grid.

LoRaWAN Infrastructure

Battery-powered sensors transmit over kilometers to a central, solar-powered gateway.

Infrastructure for Growth.

merkaio core

Deployment of Milesight agricultural sensors. Developed for harsh environments, resistant to fertilizers, UV radiation and spray water (IP67).

merkaio ops

We monitor network coverage on your fields. If a gateway fails (e.g., due to severe weather), we react immediately. We guarantee data availability.

merkaio dev

Calculation of complex agricultural metrics (VPD, GDD - Growing Degree Days) directly in the dashboard. Integration with irrigation controllers via API.

Sensors for Tough Field Conditions.

Milesight EM500-SMTC

Milesight EM500-SMTC

The Soil Expert

Soil moisture, temperature & conductivity (EC).

  • 3-in-1: Measures not only moisture but also electrical conductivity (EC), allowing conclusions about salt/fertilizer content in the soil.
  • Robust: Probes are corrosion-resistant and can remain permanently in the ground.
Milesight EM300-TH

Milesight EM300-TH

The Climate Guardian

Air temperature & humidity.

  • VPD Basis: Provides raw data for calculating vapor pressure deficit.
  • Mounting: Flexibly mountable on supports or walls in the greenhouse.
Milesight EM500-LGT

Milesight EM500-LGT

The Light Analyst

Light intensity.

  • Function: Measures illuminance (Lux) to efficiently control artificial lighting.
  • Application: Automation of shading systems or grow lights.

From Sensor to Harvest Optimization.

We visualize your data in Grafana or ThingsBoard. Specially tailored for agricultural needs:

  • Zone Map

    Visualization of soil moisture on an aerial view of your fields/greenhouses (heatmap).

  • VPD Chart

    Live calculation of vapor pressure deficit. Green = Optimal growth, Red = Fungal risk.

  • Frost Alert

    Instant notification to your phone when critical temperatures are reached.
