BACKGROUND OF THE INVENTION
In existing system, time taken for spraying pesticides in agricultural field is high compare to proposed system. The area coverage is one of the parameter for evaluating limitations of spraying pesticides by human. The area coverage and time are directly proportional to each other. For large area, time taken for spraying pesticides in agricultural field is more whereas for small area, time taken for spraying pesticides in agricultural field is less. In the existing system the area coverage is small compare to proposed system. The important drawback in existing system is disease. In existing system, body of the farmer is directly contact with the pesticides liquid so it will cause many harmful diseases to the farmer.

With the development of agricultural machinery, agriculture has gradually realized semi-automation or even full automation. At present, pesticide spraying in agricultural production can include handheld mechanical pesticide spraying and walking mechanical spraying. Manual pesticide spraying causes many harmful side effects to the personnel involved in the spraying process. For handheld pesticide spraying, laborers still need to carry spraying equipment to the pesticide spraying. On the other hand, walking mechanical pesticide spraying has many has many problems, such as difficulty to getting down to the field, low travel speed. As the flying technology of small and medium-sized drones gradually matures, the drones have advantages of the vertical take-off and landing, and make it possible to pesticide spraying the drones.

This even allows multiple UAVs to be used for a single application. In this case, the UAVs must have communication facilities so that they can communicate with each other. This can easily be achieved by equipping an UAV with a wireless mesh node.

turning on pump and sucking pesticide from a pump to the nozzles [24];
transmitting signals from a transmitter [32] of the control device and receiving received by a receiver [34] in the remote controlled heavy lift spraying device [100];
transmitting the received signal to a flight controller [35] where the signal is processed with the sensors;
sending the processed signal to an Electronic Speed Controller (ESC) [42], which allows the specific amount of current to a motor [21] based on the signal it receives;
mechanically coupling the propellers [14, 15] to the motors [41] so that they rotate and produce thrust. An imaging unit [30] preferably a first-person view flying (FPV) camera takes current supply from the flight controller [35].
recording the video by the imaging unit [30];
processing the video signals by the transmitter [32] of the control device and receiving by the receiver [34] in the remote controlled heavy lift spraying device [100]; and the pump takes current supply from a power source [36] preferably a Li-Po battery and pressurizes the liquid from the sprayer pump,

A hexacopter is controlled autonomous with the help of GCS which controls the flight. Sticks on the controller allow movements in different directions and trim buttons allow the trim to be adjusted to balance the drone. Screens are used to receive live video footage from the on-board camera and to display sensor data.

On-board sensors provide helpful settings such as Auto altitude where the hexacopter will move at a fixed altitude, and GPS hold, where the hexacopter will remain at a fixed GPS position. Hexacopters are flown autonomously, modern flight controllers can use software to mark GPS waypoints that the vehicle will fly to and land or move to a set altitude.

Frame – the skeleton of the drone which all components are fixed to. The chassis design is a trade-off between strength and additional weight, which requires longer propellers and stronger motors to lift. Propellers – principally effect load the hexacopter can carry, the speed it can fly and the speed it can maneuver. The length is modified; longer propellers achieve greater lift at a lower rpm but take longer to speed up/slow down. Shorter propellers change speed quicker and thus are more maneuverable, however they require a higher rotational speed to achieve the same power as longer blades. This causes excess motor strain and thus reduces motor life span. A more aggressive pitch will allow quicker movement but reduced hovering efficiency.

Motors – one per propeller, drone motors are rated in “Kv” units which equates to the number of revolutions per minute it can achieve when a voltage of 1 volt is supplied to the motor with no load. A faster motor spin gives more flight power, but requires more power from the battery resulting in a decreased flight time. Electronic Speed Controller (ESC) – provides a controlled current to each motor to produce the correct spin speed and direction. Flight Controller – the onboard computer which interprets incoming signals sent from the pilot and sends corresponding inputs to the ESC to control the hexacopter. Radio Receiver – receives the control signals from the pilot. Battery – generally lithium polymer batteries are used due to high power density and ability to recharge.

The 6 propellers of a hexacopter are fixed and vertically orientated. Each propeller has a variable and independent speed which allows a full range of movements.
Sprayer module has two sections, they are 1) Transmitter section (Remote controller), 2) Sprayer with controller. Transmitter section used to control the actuator of sprayer module. The nozzle of sprayer module is activated by remote control. Wherever need to activate the sprayer, just comment by remote RF transmitter.

Sprayer module contains two sections, spraying module and controller. Spraying module contains the spraying content i.e., pesticide or fertilizer and the controller section used to activate the nozzle of sprayer.

The command is received from remote controller which is activated manually. Tank contains the chemical content which is going to spray on crops that may be a pesticide or fertilizer. The Nozzle of the sprayer module is activated by GPS device. This GPS module comprises of the preloaded GPS coordinated. The sprayer pump is preferably a brushless pump. The camera is preferably a multispectral camera. The power source preferably comprises of battery and the like. The computer instructions are received from the controller which is activated manually.
