UAV-Based Chemical Dispersal for Agriculture & Hygiene

UAV-Based Chemical Dispersal for Agriculture & Hygiene

Aerial application of agrochemicals and disinfectants demands precise droplet sizing, controlled release altitude, and comprehensive coverage pattern planning. This heavy-lift hexacopter integrates a tank, pump, and boom-mounted nozzles calibrated for the target liquid's viscosity and surface tension. Flight planning software generates lawnmower-pattern waypoints adjusted for wind speed and direction, ensuring uniform application rates across the target polygon. Real-time flow sensors and tank load cells enable variable-rate application, reducing chemical overuse in low-pest-pressure zones. For sanitization missions, the system disperses hypochlorite or quaternary ammonium solutions over large public areas, dramatically increasing throughput compared to manual backpack sprayers while minimizing human chemical exposure.
