Could anyone plz give me details of the GL sensor numbered
GL 40T-16F/16S

This is an ultrasonic transmitter-receiver pair tht i found in a shop.. But i have no details abt it.

[thommichhan]

what about the range of this pair?
40T-40R


In my project , i employed this component but the receiver is not working properly.
Noise is more and not catching the signal transmitted.
Any suggestions? Plz help

Also could you plz suggest a method to check this pair.
