Development of Cost-Effective Precision Spraying Techniques Using Sensor Technology

Abstract

An extremely useful mechanism in the agriculture industry for efficient crop production is spraying activities. The current spray methods are inefficient. Spraying at a variable pace is the best option in this case. The size of the tree canopy must be accurately estimated in order to spray pesticides at variable rates. Due of the diverse growing structures and different plant sizes, it is difficult. Trees are seen to have a variety of shapes and dimensions throughout the growth seasons. It is vital to take into account elements like tree height, width, diameter, and total canopy volume in order to assess this alteration. The amount of a tree’s canopy is calculated in this study utilizing ultrasonic sensors, controller and a spraying mechanism is constructed in proportion to the volume of that plant. The ultrasonic sensor, controller and spraying mechanism are all part of the system. With the aid of sensors, geometrical properties of the tree are identified. A series of experiments were carried out on samples of plants with various sizes and forms. For plant sample applications, liquid pesticide savings were greater than a traditional application. Results demonstrated no discernible difference between tree canopy volumes estimated by ultrasound sensor and by person. The procedures for variable rate spraying techniques in orchards are presented in this article. The study of the creation of cost-effective precision spraying techniques using sensor technology is the major contribution of this work. Out of all of these strategies, this study will assist in selecting and designing the most effective and affordable way for a precision sprayer.
