Abstract
Pesticide spray is essential for pest control, crop production and protection. However, the direct contact of these pesticides with humans may cause cancer, complication in the respiratory system and neurological disorders. This problem is more severe in developing countries as each year more than 100 thousand death cases are reported by World Health Organization. This work presents a modification approach of Quadcopter into a UAV, in such a way that it can fly in manual as well as autopilot mode and can spray on agricultural lands using its ground control station. In this work, a stable system is developed for aerial distribution of pesticides as well as fertilizer to reduce human contact with pesticides. The system consists of; a) a remote controlled UAV (Unmanned Aerial Vehicle) which is controlled from ground through a flight controller and b) a spraying system which is manually triggered by RF controlled circuit. The reliability of the proposed framework is evaluated on a test area of around 1000m2. The pumping rate of sprayer system is adjusted to 40 mL/min with PWM at 45% duty cycle. From results it can be concluded that the integration of UAV with the spray system results in a spraying mechanism which is very efficient and hazard-free for crop pest management in the small field area.

Modern technology is benefiting us in many ways
After going through literature review and checking different electronics equipments we found the ArduPilot Mega (APM) as a stable and operating controller which has built in calibration components like compass and accelerometer
A precise mechanism for aerial spraying by modifying a quadcopter has been presented
Summary
Modern technology is benefiting us in many ways. Dependency on scientific means to get quality product on economical prices has been increased. Agriculture is adapting modern means of technology to increase its productivity with minimum financial resources. One of the major factors that increases the agricultural product is the timely and accurate distribution of the pesticides. Pakistan which is an agricultural country highly needs to adopt modern mechanisms and replace conventional mechanism of farming with modern technology. A framework based on quadcopter is used to distribute pesticides on the crop by knowing the coordinates of a given field. The purpose of this prototype demo was to compare the accuracy of the pesticides distribution with conventional mechanisms and conclude the financial differences in both the processes
