Description
Main Types of Agricultural Drones
Monitoring / Mapping Drones
Used for collecting crop data and field analysis.
Functions:
-
Crop health monitoring
-
NDVI imaging (plant health index)
-
Soil condition mapping
-
Irrigation planning
-
Detecting disease or stress early
Typical Features:
-
High-resolution RGB cameras
-
Multispectral cameras
-
Thermal sensors
Spraying Drones
Used for applying liquids or granules.
Applications:
-
Pesticides
-
Herbicides
-
Fungicides
-
Liquid fertilizers
-
Seeds (in some models)
Advantages vs traditional spraying:
-
Uses 30–50% less chemicals
-
No soil compaction
-
Safer for workers
-
Works on difficult terrain
Planting / Seeding Drones
-
Used for reforestation and cover crops
-
Can plant thousands of seeds per day
Sensors Used in Farming Drones
| Sensor Type | Purpose |
|---|---|
| RGB Camera | Visual crop inspection |
| Multispectral | Plant health, chlorophyll levels |
| Thermal | Water stress detection |
| LiDAR | Terrain and elevation mapping |
How Farming Drones Work
-
Drone flies over the field
-
Captures images & sensor data
-
Software processes the data
-
Farmer receives:
-
Health maps
-
Pest/disease zones
-
Irrigation recommendations
-
Yield prediction
-
This is called Precision Agriculture.
