Wireless data trasmision.

[Aneesh Bharath]

Hai..

Is it possibile to trransfer signal from a sensing device wirelessly to a reading system.

I have a light sensor and a rande finder and want to transfer both the output signals to a microcontroller to process it!

Can it be done using RF modules? how can i do it?

The data can be send by wireless module serially, hence only one data can be send at a time, if you need to send two data bytes, it can be done only one after another. Basically you should design your own protocol for the data transfer.

thank u..
how do i do dis?…wat kind of wireless module do u suggest?

[AJISH ALFRED]

You can use commonly available TWS434 and RWS434.

I suggest you the idea which I’ve once implemented successfully. (sorry I don’t have the code back up)

 

Suppose A and B are the bytes to be send. Take two more bytes X and Y. X represents the next data transmitted will be A and Y represent next data transmitted will be B. Now send in the following format and do the coding in the transmitter and receiver part accordingly.

Hope it helps.

Aneesh, can you tell in which format you are getting signals from sensor. I mean it is in voltage or PWM or Serial data. Then i can help you.

basicly i want to transfer info frm a sensor o/p wirelessly to a display system..

 

any ideas?

 

 

will using a RF module wid a suitable encodr-decoder help?
