A. Introduction:
Facing with the challenge of saving power, significance of national issues, while improving the convenience of field control - one of the factors to determine the development of the country, the implementation of the project "control and monitor electrical devices using RF remote" is for the purpose of industry’s control devices application. B. Project objectives:
The main aim of this project is achieved through these objectives: 1. Research operating principles of RF transceiver modules. 2. Research operation of coding and decoding of IC PT2262/PT2272 pair. 3. Practical application of AT89S52 microcontroller chip and Keil C software. 4. Build control algorithms and monitor devices. 5. Write a program to control and monitor devices. 6. Calculation, design, construction supervision and control circuit devices. 7. Remote Control: Turn on/off devices remotely via RF transceiver module. 8. Manual control: Turn on/off the device manually via buttons mounted on the board. 9. LCD display on circuit board shows operating status of the device.
C. Project specification:
Content project is divided into 4 chapters and is organized as follows:
Chapter 1 Introduction: an overview of the contents of the subject - issues will be considered in the full article.
Chapter 2 Theoretical Foundations : This chapter will go deeper theoretical of RF transceiver, operation of encoding and decoding IC PT2262/PT2272 pair, LCD 16x2 theory , and AT89S52 microcontroller.
Chapter 3 Calculation and system design: refers to the specific calculations to design hardware system including block diagram, functions and operations of the block, research algorithm and write code for the microcontroller program.
Chapter 4 Results and development: the results of the examination system, the advantages, disadvantages and development of projects.
D. Implement:
