This document describes a project to develop a PLC-based automatic bottle filling and capping system. The system will include a filling unit with a reservoir, pump, and solenoid valve. An infrared sensor will detect empty bottles on a conveyor belt and activate the filling unit. Once filled, the bottles will continue on the conveyor belt and be capped before exiting. The project aims to create an efficient and low-cost automation solution. A budget of approximately Rs. 3000 is estimated for completion. The goal is to gain experience with industrial automation processes like filling and capping using a PLC.
