Agromist: Design and Development of an Aerial Pesticide Spraying Drone for Precision Agriculture

Agriculture is very important for feeding the increasing number of people, and protecting crops effectively helps

increase harvests and make farming more sustainable. Using traditional methods to spray pesticides is hard work, takes a lot of

time, and can harm farmers' health because of exposure to dangerous chemicals. To solve these problems, this paper introduces

AgroMist, a drone that sprays pesticides from the air using a hexacopter. The system is made with a ZD850 hexacopter frame, a

Cube Orange flight controller, a GPS module, brushless DC motors, electronic speed controllers, and a spraying system. The

drone can be operated either by hand or automatically using Mission Planner software. It helps spread pesticide evenly and

reduces waste. How it works is by using the flight controller to process signals and control the motor speed for steady flight. A

pump system spreads the pesticide over the crops, and the air from the propellers helps the spray reach deeper into the plants.

Test results show that the system flies steadily, moves accurately, and sprays effectively. This system makes farming safer, less

tiring, and more productive. This work highlights how drone technology can help in precision agriculture
