Foliage Condition Monitor​

Leaf Condition Monitor includes the monitoring of Leaf Wetness, Air Temperature, Leaf Surface Temperature, CO2, Humidity, Wet-bulb temperature, Dew Point, Aeration, Evapotranspiration / Respiration



FOLIAGE CONDITION MONITOR:-Foliage conditioning is a Photometric  device which uses the IOT sensors for the measurement of Leaf Area Index, Water loss/Water deficit stress in plants by real time monitoring of foliar diseases, moisture level in plant leaves for efficient growth and by optimizing the canopy.


  • Leaf wetness
  • Leaf Surface Temperature
  • Air Temperature
  • Humidity
  • Carbon dioxide
  • Aeration
  • Evapotranspiration/Respiration
  • Dew point


  • Minimize the nutrient deficiencies and justify the nutrients supplied to the plant
  • Minimize the foliar diseases
  • Imitates characteristics of a leaf
  • Doesn’t require painting/calibration of individual sensors
  • Detects trace amounts of water/Ice on the leaf surface
