how to know if an IR sensor is TX or Rx?
they are the same color(white). is there any way how to test it?
or anything of the two can be use Tx and Rx? tnx..
 

I don't know of any IR sensor that is white in color. Do you mean transparent?
In general, check the device datasheet.
Also, you need to consider your question. Does it make sense for a sensor to be a transmitter?
What generates IR transmissions? If you had to transmit IR, what kind of device would you consider using?
It will answer your own questions!

Hi Mymelon,
Ya both looks identical (like white LED), but you can identify it
1 make a simple ir receiver circuit.
2 put the device in it and test applying ir light on it.
3 if it receives it is RX otherwise TX
