this page gives information of our final year project...    

                                      Our project is wireless data transmit ion. here transmitter send data to control room(upto 300 ft). and control room send data to receiver 1 or receiver 2 (upto 300 ft).

our transmitter data is temperature, that is display on control room using LCD. when incoming data is <40 or >40 receiver 1 or receiver 2 communicate with the control room. and one operator is sitting on control room for sending information like 'A', 'B', 'C', 'D'  form control room to the receiver 1 or receiver 2. and that data ('A', 'B', 'C', 'D') is display successfully (also wireless) on receiver 1 or receiver 2 .

receiver 1 and receiver 2 is nothing but two motor(car).

so acording to transmited message form control room driver can take a decision.

NOTE: ALL WIRELESS DEVICE WORK ON SAME FREQUNCY SO WE CAN CONNECT MORE NUMBER OF RECEIVER (2^10).
