In emerging era there is lot of innovation are made in agriculture field to enrich the production and maintenance of crops with reduced area and labor. We planned to introduce an optic in sky unmanned aircraft to fertilize, surveillance, nebulizer [1], growth monitoring and Yield analyzing purpose. This paper helps for crop feeding and treats pests. The OUA [2] has a special sprayer that can spread the minimum level of drugs over crops for the purpose of pest control during mid or late stages of development, food it in proper timing. In which used 64 channel GPS [3] for autonomous Driving by using Latitude, Longitude, Altitude and Speed it act as an tracker of OUA. The controllers are done in remote location using laptops/android devices when it is in autonomous mode. 2.4 GHz zigbee transceiver act as a communication channel between OUA and laptop/android devices .Pest identification is done by means of capturing the image of the crops using HD wireless camera if there is any variation in crop color then the spray pump will spray fertilizer or organic pesticides. The amount of pesticides sparing is determined by the infection rate of the crops, infection range is calculated through digital image processing by comparing and analyzing pixels of the crop image. Digital compass provides driving direction for OUA. Ultrasonic transducer determines the height of the optic unmanned aircraft. DSP processor is used for image processing in OUA. Growth of the crop keyed by changes in crop color and yield analyzing is done by capturing RGB of the crop means of continuous surveillance .It operates on solar power. The plane can prevent crop damage caused by traditional mechanical work and increase economic returns.
