ABSTRACTThe main aim of this project is to control the electrical devices

using RF technology. This project gives the best solution for electrical power

wastage. This project does this application using wireless concept. One of wireless communication system is RF (Radio

frequency) communication system as it is very cheap and very easy to implement.

RADIO FREQUENCY

Radio frequency is a frequency or rate of oscillation within the range of about 3 Hz to 300 GHz.

RF is widely used because it does not require any line of sight, less distortions and no interference

LCD

The 2x16 Serial LCD panel displays up to two lines of text, with up to 16 characters on each line.

The Parallax Serial LCDs (liquid crystal displays) can be easily connected to and controlled by a microcontroller using single I/O pin. 

The LCD displays provide basic text wrapping so that your text looks correct on the display.

TRIAC BT136 TO-220

TRIAC (Triode for AC) is the semiconductor device widely used in power control and switching applications.

It finds applications in switching, phase control, chopper designs, brilliance control in lamps, speed control in fans, motors etc.

SOFTWARE PROGRAM

Low cost and reliable Can transmit up to 10 meters Highly sensitive System can be switched into manual mode whenever required

Hotel lights/fans control Home appliances control Industrial applications

CONCLUSION

The project “RF BASED INDUSTRIAL WIRELESS DEVICES CONTROL SYSTEM” has been successfully designed and tested
