Mini controlador lógico programável

Abstract

The programmable logic controllers (PLCs) are electronic devices used in automation systems, which are very useful tools for applications in control system being widely used in industrial and residential market. PLCs are widely accepted because is easy to change programmed logic. This aims of this project is the development of a low cost Mini Programmable Logic Controller for both industrial and home automation. Motivated by the need for an intelligent drive and a market in constant evolution are in automation in the world, it is observed that more and more people seek the comfort and ease of handling devices in the everyday. With this objective, the product will be available to professionals enabling the automation of control devices and equipment. The Mini PLC is a robust controller and consists of small, uniting technology and low cost alternative in automation. The development was done with PIC18F452 microcontroller; the system has eight digital inputs, four digital outputs and USB interface for user setup convenience.
