eBay Ultrasonic R+T

[adanvasco]

Hello fellows.

I found this pair of emitter/receiver on eBay a few days ago:  http://www.ebay.com/itm/1Pair-R-T-Ultrasonic-Transducer-Sensor-Source-Receiver-/300553606556

I just would like to know if by reading the seller's specs you can tell if these are good enough for a range finder.

Thanks in advance,

Adan.

Hi,

They should be fine for the purpose

Thanks Soeren.

I thought so too, but wasn't really sure as I've never made anything like this before.

Thanks a lot.

Hi,

Looking forward to see your results

If you get into trouble with the direct (unreflected) signal desensitizing the receiver to the ping (reflected), you can make a "collar"/tube of something like foamed neoprene/rubber around each of them to minimize this.
