Multispectral Sensors for Drones

 
Multispectral Sensors
Multispectral sensors are specialized cameras that capture reflected light in several spectral bands invisible to the human eye. In agriculture, they are used for detailed diagnostics of crop health, soil conditions, and water balance.

Key capabilities of multispectral sensors in agriculture:

  • Blue — analysis of leaf structure, detection of damage and chlorophyll deficiency.
  • Green — assessment of overall plant health and vegetation density.
  • Red — monitoring photosynthesis and crop maturity.
  • Red Edge — early detection of plant stress and nutrient deficiency.
  • Near-Infrared (NIR) — determination of moisture content and biomass.

Advantages of use:
  • Early detection of diseases and plant stress before visual symptoms appear.
  • Creation of NDVI, NDRE, GNDVI, and other vegetation indices for precise agricultural planning.
  • Optimization of fertilization and irrigation through accurate field condition mapping.
  • Reduced costs and increased yields by integrating data into precision agriculture systems.
MicaSense Series
MicaSense manufactures professional multispectral and thermal cameras designed for agricultural monitoring, compatible with most industrial drones (including DJI Matrice 300/350 RTK via adapters).

Main Models for High-Precision Tree and Leaf Scanning:

  • MicaSense RedEdge-MX — compact multispectral camera with five channels (Blue, Green, Red, Red Edge, NIR), optimized for NDVI, NDRE, GNDVI generation.
  • MicaSense Altum-PT — combines multispectral, thermal, and high-resolution panchromatic channels, capturing detailed RGB imagery, thermal maps, and vegetation indices in one flight.

Applications:
  • Vegetation index mapping
  • Photosynthetic activity assessment
  • Stress and disease detection
  • Water regime monitoring and irrigation planning
  • Growth monitoring and yield estimation
