How Do Agricultural Drones Work?

Agricultural drones (farm drones or precision agriculture UAVs) are unmanned aerial vehicles that fly over farmland to capture aerial imagery, spray chemicals, spread seeds, and collect sensor data. They use GPS waypoint navigation, multispectral cameras, thermal sensors, and AI-powered image analysis to provide farmers with actionable intelligence about crop health, pest pressure, water stress, and more.

Quick summary:

  • What sensors do farm drones use?Farm drones use RGB cameras for visual inspection, multispectral cameras (NDVI, NDRE) for crop health analysis, thermal sensors for water stress and irrigation monitoring, and LiDAR for terrain mapping and plant height measurement..
  • Do you need a license to fly a farm drone?In the US, commercial agricultural drone operators need an FAA Part 107 Remote Pilot Certificate. Most countries have similar requirements.
  • How much does an agricultural drone cost?Mapping/monitoring drones start at $2,000-5,000. Multispectral survey drones cost $5,000-15,000.
