ABSTRACT This paper presents the design and development of a wheel-operated sprayer tailored for agricultural use. The sprayer integrates ergonomic design principles with efficient spraying technology to enhance ease of use and productivity in farm operations. Key features include a robust frame mounted on a wheelbase for mobility, a user-friendly control interface and adjustable spraying parameters for various crops and terrains. Additionally, the sprayer incorporates environmental friendly practices through precise chemical application, minimizing wastage. Field tests demonstrate its effectiveness in improving spraying efficiency while reducing operator fatigue, making it a valuable asset for modern agricultural practices. In this project, We executed the IoT for rotating the nozzle for 180 degree using servomotor. Servomotor is used to control the direction of nozzle. We control the servomotor through Potentiometer. 1. INTRODUCTION ...
