One of the emerging technologies is pesticide spraying using drones. Manual pesticide spraying has a number of negative consequences for the people who are involved in the spraying. Operation, the result of exposure symptoms can include minor, skin inflammation and birth abnormalities, tumors genetic modifications, nerve and blood diseases, endocrinal interference, coma or death. However, drone can be used to automate fertilizer application, pesticide spraying and field tracking. This paper provides a concise overview of the use of drones for field inspection and pesticide spraying, displays different methodologies and controllers of agriculture drone and explains some essential drone hardware. Software elements and applications keywords, drone technology, spraying, pesticides, crop monitoring. One introduction: the explosion of the human population makes high productivity, high performance and sustainable agriculture more important one in the modern environment. Agriculture is essential for the subsistence of more than 60 percent of total of the worlds population. Two. It is a critical element in the protection of the environment in the developed world. The agricultural modernization is mandatory when demand and food supply are increased. Drone are one of the most advantageous equipment for modern agriculture. The pesticides and fertilizers are critical components in the control of insects and the development of crops. Spraying pesticides and fertilizers by hand causes tumors hypersensitivity, allergies and other illnesses in people. Hence, drone can be used to automate fertilizer application, pesticide spraying and field tracking, which is also used for many applications, such as search and rescue police code inspections, emergency management, fire other advantages of drones include their fast maneuverability, improved payload, high lifting power and stability 3.

. It comes with a universal sprayer for spraying, both liquid and solid contents, the global nozzle sprays, all pesticides and fertilizers, but the tension pump is only used when spraying pesticides and not when spraying fertilizer in wide fields. The gps can be used to automatically direct the quadcopter and power it remotely. A quadcopter is piloted by an autopilot controller and the payload is driven by an rf transmitter and motors. The figure one illustrates the pesticide spraying mechanism for this paper usually depicts the characteristics of appropriate drones for a particular agricultural purpose. Furthermore, it will be clear as to which drone archetype is needed for specific farming tasks. The systematic review of this article is based on basic keyword and abstract searches in scopus woes web of science and google scholar databases. Several trustworthy websites were also consulted for subject related material 2. literature review, yalapa 2017 improved in hexacopter with 6 bldc motors and 2 lipo batteries of 6 cells, 8 000 mah. Their research also includes a performance assessment of spray, liquid discharge and pressure spray, liquid depletion and droplet size and density determination by means of their project. They eventually created a drone that can hold 5.5 l of liquid and has a 16 minute endurance period. 5.. Dongian 2015 investigated successful, swath width and droplet distribution uniformity over aerial spraying systems such as the m18b and thrush 510 guanis, the agricultural planes flowered respectively, at 5m and 4m high and by this experiment. They conclude the disparity in swath width of m18b and thrush 510g in flight height 6.

, professor b balaji 2018 created a hexacopter uav for pesticide spraying, as well as crop and environmental surveillance using raspberry pi and the python programming language. Their uav also has a variety of sensors, including dh11 ldr and water level, monitoring sensors. As a result of this experiment, they eventually concluded that with proper implementation of uavs in the agricultural sector, savings in terms of water, chemical abuse and labor can be projected to range. Between 20 and 90, 7. kirkut 2018 used basic cost efficient equipment to work with uav quadcopter and its spraying system spraying, with both liquid and solid material is done using the universal sprayer method. During their analysis, they also compared various agricultural controllers and came to the conclusion that the quadcopter system, with the atoga 644 pa, is the most suitable. Due to its successful implementation, eight huang 2015 developed a low volume sprayer that can be used in unmanned helicopters. The helicopter has a 3m main rotor diameter and a payload capacity of 22.7 kilograms. It used to take at least a gallon of gas every 45 minutes. This research paved the way for the development of uav aerial application systems for crop production, with a higher goal rate and a larger vmd droplet scale. 9. shilpa kidari has suggested a low cost lightweight quadcopter qc framework. The quadcopter is also known as unmanned aerial vehicle uav. This quadcopter is compact and can be used for both indoor and outdoor crops. The quadcopter is an unmanned flight that uses an android smartphone to spray pesticides and fertilizer.

The contact between the quadcopter and the android smartphone is achieved in real time using a bluetooth device. This method is used to reduce agricultural field problems, while still increasing agricultural yield, 10. sadhana improved on the above approaches and created the quadcopter uav and shower module which can be used to spray pesticides in agriculture fields to increase efficiency and protect materials. The total load for this project is one kilogram and is used to spray low altitude pesticide quadruple, copter lift the arduino uno at mega328 and brushless direct current bldc electronic speed control esc mpu 6050, which combines a mems accelerometer and a mems gyro into a single chip. Radio receiver, lipo battery and pesticide spraying module control, this quadcopter 11., three methodologies and materials methodologies. The main board in the drone is the flight controller, which is loaded with cutting edge firmware and is in charge of the actual flight. The flight controller controls a lot during the flight or drone. At the same time, it has been designed and connected with a microcontroller to the four motors without brush motor bldc motor attach in the drone setup model with the rotors. These bldc motors are controlled by the electronic speed controllers esc. The drone is powered by the transmitter and receiver of the radio network. There are several platforms for individual drone control activities for any rc transmitter. A sample block diagram shown in fig four different methodologies and controllers of drone are shown in table three.

The quadcopters enable the fabrication of unique folding frames for safe transport and convenient packaging of cylindrical cushioned boxes, accelerometer, gyroscope, imu, infrared camera, bldc, esc drones are an array of sophisticated hardware, software and advanced technology in general. Many software and hardware components are used to properly control the drone. According to drones, startling variants, the unified body or structural components are usually referred to as hardware drone hardware shows the technical components of the drone enough and takes software applications guidance. Furthermore, the software may be referred to as a drones brain the software is supposed to tell the drone whether or not to go and what to do as a potential method of speculating and combining all of the drones critical data. A complicated structure benefits from the software portion drone software consists of a large number of different applications, processes and operations. It also has a specific liability, as shown by its hardware components.
