Ornavera

ROBUST AND EASY TO INSTALL

Installation can be made in less than 5 minutes. Decide your measuring point, put the sensors where you want them, and press the ON button.

DIFFERENT SENSORS

Our system deliver wide variety of sensores, so that growers can benefit from measurements of climate, soil and plant data. All devices can be customized depending on growers needs.

• Climate
  • PAR / Photosynthetic Active Radiation
  • Air Temperature
  • RH/Relative Humidity
• Soil
  • VWC/Volumetric Water Content
