They are made by a Taiwan company called Pro-Wave in case you were wondering.

Almost any surplus place; All Electronics, Electronic Goldmine, etc.
Or search ultrasonic transducer on ebay.

futurlec has them. If you ask, they will send you the specs.

Bought a ParkZone parking aid for $3 at a flea market a while back. There is a PIC 12C508(9?) that runs the show along with a precision voltage reference, comparator, op-amp, and such. Have yet to interrogate the Pic to get the pulse frequency and lengths though (send and receive). The single sensor one looks to be a Polaroid style. Those Polaroid cameras can be found cheap at thrift stores too.

Note to self: get it working, to turn on the sprinklers, and spook the neighbor's dog before he lays a large land mine again in the yard.

I am confused. Do you want the transducer component, or the Ping Bracket assembly?

just the transducer. Or transmitter and receiver separate

Were the surplus links I posted helpful, or are more hints needed?

24KHz Ultrasonic Transducer-The Electronic Goldmine

Thats a nice price but whats the range on that?

Wow!!
**broken link removed**

10 @ $1 each. Now you cant beat that

someone (customer comment) said it has a 9ft range which is same as my parallax brand board. So i think this is very cool!

The range is highly dependent on the circuit.
