can anyone explain how can ultrasonic sensors can be used as only transmitter or only receiver????

You basically cover the transmitting transducer on one of the sensors. You trigger both devices but sound only comes from one of them. If you don't need to receive the echo from the transmitting unit, you can just ignore the resulting echo pulse.
The unit with the blocked transmitter sends its pulse into the obstacle blocking the transmitting transducer (foam, tape etc.) and ends up receiving the signal (which it treats as an echo) from the other unit.
I discuss a possible application for this sort of thing in this post.
As I mentioned in the other thread, this "trick" only works with sensor which use separate transducers to send and receive ultrasound. The single transducer sensors such as the ones made by Maxbotix couldn't be used this way.
We have tried that but the result is not as we expected.....
I have removed the transmitter of one sensor and receiver of another and checked whether the ping is receiving or not....
but i didn't get any response can you please solve this....
Thanks
