This document describes a project to develop a PC-based industrial automation and security system. The system uses a microcontroller to control loads, appliances, and security in industries through a PC and touch screen interface. It has three modules: load control, fire alarm, and security locking using RFID. The system automates industrial processes to increase productivity, quality and consistency while improving security. Hardware components like the transformer, regulator, rectifier, and filter process power for the microcontroller and other components.
