PC Based Device Control

Aim:

In this project we are going to Turn ON/OFF Devices via PC.

Introduction:

A very simple Graphical User Interface (GUI) will be provided using which on single click the user can control devices. On clicking the software sends data serially to our microcontroller via the serial port. The controller receives the data & decodes it and accordingly Turns ON/OFF the relays connected to it.

Hardware Requirement:

1. Microcontroller: 89S52
2. Max232.
3. ULN 2803, Relays

Software Requirement:

1. Keil Software as Compiler.
2. Proteus for Circuit Designing.
3. Protel for PCB Designing.
4. VB software.

Advantages:

1. It is economical
2. NO manpower required
3. Multiple Devices can be switched ON/OFF by single click.

Application:

1. Home Automation
2. Shops & show rooms.
3. Hotel Lights & Fan control.
4. Street Light Management.
5. Valve Control in SCADA systems.
6. Hotel Power Management.

Future Scope:

1. Devices can be controlled via GSM.
2. Bluetooth can be used.
3. The communication between the PC & the controller can be made wireless
