Embedded Project on Unique Office Communication System Using RF


This project is a PC based communication tool in office for data(text) transmission to an individual or multiple users utilizing radio frequency technology.

In many offices, if an employer has to convey a message to a particular employee or a group of employees, he has to call them personally or send the message through another person. But there is a possibility of a message to be misinterpreted and there is wastage of time.

In this proposed system, the employer in an office will have a transmission module while the employer will have one receiver module each. If the employer wants to convey any message to employees or any particular employee, he can send it through the transmitting module which is associated with the PC.

Receiver section comprises a module which receives the information and feeds to the microcontroller that displays the message on a LCD. A buzzer interfaced to the microcontroller on the receiver side, which gives the suggestion that information is received. Adopting this technique one can eliminate the need for a third individual for correspondence, with the goal that the exact message is delivered to the desired person.

This project in future can be enhanced, by including a component of two-way communication between the employer and the employee(s).
