outdoor "car" type ultrasonic range sensor

P

Phil

You may have seen ultrasonic range sensors on the rear of many late model
cars. Where does one buy a set from at a reasonable price? I want to make
this kit up:

but it comes with the usual sensors which are probably not immune to the
elements. By the way, microzed are selling these at $48. Has anyone seen
anything cheaper anywhere? I need at least 3.

Cheers,
Phil

Farnell sell some sealed units, from memory they are about $20 each.
