The project is a wireless message communication system that enables communication between two computers by making use of 2.4GHz trans-receiver units. The project can be used in offices for communication between employees or managers. For initiating real time bidirectional communication wirelessly a pair of 2.4 GHz transceiver modules is used that are provided 5volt DC and alarm circuits. A buzzer is used to notify whenever one user initiates a chat or sends a message. The PCs are connected via a pair of transceiver modules with the help of a DB9 (De-Sub) connector and serial data cord. RS232 protocol is used between the modules and the PC for communication purpose. The trans-receiver units are supplied power by an on-board dedicated AC to DC. |
