PC to PC Data Transmission through Infrared Rays
The setup used in base of free space communication. In which communication between two PC’s is established using laser light. IC max-232 is used. IR diodes are used for short distance communication between 2-3 m. The distance could be further increase up to 100m by using laser diodes. Laser pointers available commonly are used as the laser module in the setup which has about 3 mw power as output. Laser beam from one module is made to point towards the photo diode of the other module which is connected with the personal computer and vice versa. Software module is written using c language to perform this process. His c codes are used in chatting and data transfer between nodes when line of sight must exist.
