The drone’s positive impact on innovative agriculture has yet to be manifested in the stages of land and seed preparation. One of main source of income in of India is agriculture. The production rate of crops in agriculture is based on various parameters like temperature, humidity, rain, etc. which are natural factors and not in farmer’s control. The field of agriculture is also depending on some of factors like pests, disease, fertilizers, etc. which can be control by giving proper treatment to crops. Pesticides may increase the productivity of crops but it also effects on human health. So the main aim of this project is to design agriculture drone for spraying pesticides. In this project, we are going to discuss architecture based on agriculture unmanned aerial vehicles (UAVs). The use of pesticides in agriculture is very important to agriculture and it will be so easy if will use intelligent machines such as drones using new technologies. This gives the general idea about various technologies used to reduce human efforts in various operations of agriculture like detection of presence of pests, spraying of UREA, spraying of fertilizers, etc. The development of quad copter UAV and the spraying mechanism. In this project we also discuss integration of sprayer module to quad copter system. The discussed system involves designing a prototype which uses simple cost effective equipment like BLDC motor, Flight controller, ESC wires, etc. The hydrogen fuel-cell drones are most common now-a-days and there are different types of drones, it’s quite common to imagine Zeppelins, weather balloons and similar uses of hydrogen in lighter-than-aircraft to lift stuff of the ground. But with smaller and more efficient fuel cells, hydrogen is gaining its place in the drone field. Drones are definitely getting more diverse and innovative as they play a more relevant role in our everyday life. The most significant problem with drones today is that they have a remarkably limited range. Most commercially available options can only fly for 25 minutes or less due to issues with battery capacity. Fuel cells provide greater energy density, so they can give drones longer ranges. Fuel cells require hydrogen to produce power, and the air provides a ready supply of the latter. As a result, fuel cell-powered vehicles only need to carry half of their fuel, reducing weight and extending their range. Hydrogen is also less dense than air, so fuel cell-powered drones could be far lighter than battery- powered alternatives. With less weight to carry, these drones could travel farther with less energy.
