A Comprehensive Survey on Semi-Automatic Solar-Powered Pesticide Sprayers for Farming

In recent years, the agriculture sector has witnessed a growing demand for sustainable and efficient pest management solutions to enhance crop yield and reduce environmental impact. Among these solutions, semi-automatic solar-powered pesticide sprayers have emerged as promising tools for farmers worldwide. This paper presents a comprehensive survey of semi-automatic solar-powered pesticide sprayers designed for farming applications. The survey begins by exploring the motivations behind the development of solar-powered pesticide sprayers, emphasizing the need for environmentally friendly alternatives to traditional pesticide application methods. It proceeds to examine the key components and functionalities of these sprayers, including solar panels, rechargeable batteries, pumps, nozzles, and control systems. Special attention is given to the integration of solar energy harvesting mechanisms and their impact on operational efficiency and sustainability. Furthermore, the survey investigates the design considerations and technical challenges associated with the development of semi-automatic solar-powered pesticide sprayers. Topics such as system autonomy, spray coverage, pesticide dosage control, and user-friendly interfaces are thoroughly discussed. Additionally, the paper highlights recent advancements and innovations in the field, including the incorporation of smart sensors, GPS technology, and data analytics for precision spraying and monitoring.
