The project Embedded based customized wireless message circular system for college industries makes use of 89S51 microcontroller. This is a highly flexible and cost viable solution. The power supply is used to supply a constant power of 5V to the different IC’s in the circuit. An encoder is a transducer which is used to convert data from the given format to the required format to save and speed up operations.
Today’s world is dominated by computing systems. This development in the fields of computers has also brought advancements in the field of communications. One of the most spectacular advancements being embedded systems.
This system mainly consists of a microcontroller, power supply unit, encoder, decoder, RF module and a LCD display unit. The use of embedded systems in this project in place of general purpose computers has the advantage that it performs a narrow range of tasks. This results in reduction of overall cost and complexity.
The decoder used here is the exact opposite of encoder which can be used to retrieve the original information. The RF module is a rate of oscillations covering the range from 3 Hz to 300 GHz that matches the range of AC electrical signals. LCD is a flexible controlling port that uses 8 bit or 4 bit. It displays the final result on screen.
The project “Embedded based customized wireless message circular system for college, industries” is designed and applied successfully. This project can be implemented to send data from a central point to all classrooms. This system to send data from one point to another is implemented with the aid of a transmitter and receiver via RF technology. Further, modifications could be done on this project by connecting GSM modem and through SMS action from mobile, controlling actions can be performed.
