Hi,
I just want to transmit my voice by a T-type ultrasonic sensor and then let another guy to hear the said voice by another R-type ultrasonic sensor at say 1 to 2 meters away.
So the receiver consists of a R-ultrasonic sensor and a headphone..
Can somebody direct me how to do so please?
I do not know what phrase I should google!?
Thanks in advance.
