How does it work?
REAL-TIME CROPMONITORING
Sensors are initially installed in the field to monitor the crops and the environment
Real-time measurements from the sensors are wirelessly transmitted over the internet
DATA STORAGE & DISPLAY
The measurements are stored securely in the AgroWebLab server in the cloud and are always available to download or view through a desktop, tablet or Smartphone connection

Weather Sensors
1. Solar Radiation 2. Wind3. Air Temperature4. Rain5. Humidity
Provides an estimate of the total plant water usage – Daily Potential Evapotranspiration (ETP) and Environmental Stress.
Vapor Pressure Deficit (VPD). Can predict daily water needs.
1. Leaf Temp Clips 2. Canopy IR Camera
Leaf Sensors
Provides information of the Stomata opening and amount of Photosyntesis– Crop Water Stress Index (CWSI).
Accumulated Stress indicates a need to change the irrigation quantity and schedule.
1. Soil Moisture2. Soil Temperature3. Tensiometer
Soil Sensors
Minimum Soil Moisture levels can be set based on the soil type. Setpoints can be adjusted based on stress indicators.
Changes in soil moisture over time are useful in defining the soil properties and setting minimum irrigation frequencies.
1. Stem Diameter2. Fruit Diameter3. Dendrometer
Growth Sensors
Changes in growth rate are continuously monitored and can detect stress immediately.
Daily Stem contractions relative to the weather conditions indicate water shortage.
