Automatic Sprayer for Crops using Arduino and Bluetooth

Crop yield is reduced by mainly due to attack of pests, diseases and weed. Chemical control is the popular method adopted for controlling most insects, weed and diseases. The chemicals are applied either by spraying, sprinkling or on the crop with help of pump or dusting. Spraying is one of the most effective and efficient techniques for applying small volume of spray liquid to protect crops. In conventional methods, manually operated low and high volume hydraulic sprayer and power operated hydraulic sprayer with long boom, long lances or spray gun are used to carry fluid at different targets. In this method, the time and labor required is more. It is difficult to spray the pesticide uniformly and effectively throughout the tree by conventional method of spraying. Though this method gives good pest control, it consumes large volume of liquid per plant, great amount of time and labor are required. Also drip losses are more. The normal farmers does not follows the instructions provided on the seals of pesticides and insecticides and due to these reasons the accidents happens. This machine will help to the normal farmer to spray pesticides and insecticides of crops without any human interception or human effort. Just use a mobile phone or a tablet to control the machine through the Bluetooth link.
