Ultrasonic Receiver Circuit

I would go to the Paralax website and pickup one of their ultrasound kits.

That purchase would give you the sensors to send and receive the signal with a nice simple Arduino interface.

Thanks!   I'm building an IR/ultrasonic beacon system and the ultrasonic transmitter and receiver must function independently. 

High David,

As I recall, these ultrasonic transducers are very directional.

You might need to rotate the transmitter to get full coverage for your beacon application.

You might want to copy the design of the old TACAN radio beacon system.

They used a rotating beacon and a rotating receiver to get pretty good directional information of the location of the transmitter in relation to the receiver.

Just a thought,

Hi DAB,

  My design is a stationary beacon system for relative position location. 

THANKS
