Ping)) ultrasonic sensor question

Question

My sensor only has a Vcc, Gnd and Signal pin on it, can i wire it with just 1 servo wire?

DJ Sures · Answer

Hey there! I've never seen a ping sensor with only 3 wires before. Are you sure there are not 4? If not, let me know the model number and i'll see if i can whip up a driver for you.

So it looks like Parallax has changed their PING))) sensor to have a 3 pin interface, I believe the SIG pin does the transmitting waits for a certain period and receives the Echo on the same pin. Dang, after all these years they have finally went to a standard 3 pin design but still haven't added analog out....grrrrr...Bad Parallax...bad!  If anyone wants to use ultrasonics I'd recommend, ironically enough, the MaxSonar EZ series by MaxBotix they can do analog or digital readouts and they are less of a cost than the PING))) and they are also a smaller form factor, seriously use an EZ-0 with the EZ-B, they are sweet!

Hi, How did you end up connecting the MaxBotix sensor, via the ADC or Pulse timing? I have several from another project that I would like to use. Thanks.

DJ Sures · Answer

Looks like I'm going to have to build support for the 3 wire ping sensor. Good idea, don't know why they didn't think of it sooner! More ping, less i/o! eek

Jeremie · Answer

@nyaple I use analog because you get a very linear voltage vs. distance readout, and it's an easy 3 pin hookup.

nyaple · Answer

Hi, Thanks for the info. I have it setup and working. I'm new to EZ-B, how do you add the Maxbotix sensor to the Ping Distance built in controls? The existing control only allos the digital interface of the Ping style detectors. Thanks, Nelson

DJ Sures · Answer

Hey Nelson, Connect the AN (analog output) from the Maxsonar to one of the 8 ADC inputs of the EZ-B. You can then use an ADC control (or the sharp IR radar control) with it

Niek · Answer

can't i just make the trigger port and the echo port the same?

DJ Sures · Answer

Interesting.... Try it and see It MIGHT just work! I'd have to look at my code and see what kind of magical spell I put on that function. Darn assembly It's harder to read then it is to write!

Niek · Answer

Then i will first need to receive my EZ-B, it has been sent +2 weeks ago but it hasn't arrived yet

DJ Sures · Answer

Really??!! That's not good. Where are you? Did you receive a tracking number?

Niek · Answer

I'm in the netherlands and did not receive a tracking number

Niek · Answer

Wait, i did get a shipment number and when i entered it in canada post, the only status is: 2011/07/25 19:25 Order information received by Canada Post

DJ Sures · Answer

Well that isn't very helpful information from Canada Post, is it? Hmm!! Can you send me a message (from the FAQ page) with your shipment tracking number and I'll get hold of Canada Post and see what's up?

Niek · Answer

Oh the mail also said: Carrier: Canada Post Service Type: International Surface Small Packets (4 - 6 weeks) stress

DJ Sures · Answer

That's strange! They are all shipped airmail. Somehow that is a mistake. I hope the entire shipment wasn't surface. Grrrrrrr

DJ Sures · Answer

Maybe there are some issues at customs in Holland? You can use the tracking number again your local mail service. You can even phone your mail service and provide them with that tracking number.

Niek · Answer

This is our post services tracking page https://www.postnlpakketten.nl/klantenservice/tracktrace/ When i try to input the item number, it wont work so i guess i'll have to call them

Hello, Since the IR sensor is discontinued, what would be the best place to add this ping sensor, without making, lets say a wall-e look weird..... thanks, Carlos.

DJ Sures · Answer

I was thinking of adding a ping sensor mounted on a small motor in his belly area. I know it isn't entirely wall-e like, but it will be functional.

TXTCLA55 · Answer

Hey Lyron, Canada Post had a huge strike awhile back. It might have delayed your package about a week or so. Either way I hope you have your EZB by now.

Niek · Answer

Nope, still haven't got it

DJ Sures · Answer

Some people from that shipment have just received theirs yesterday. I have no idea what happened with that shipment, normally it only takes a few days

Niek · Answer

From the people who received theirs yesterday, where there any that live in holland? And i know what happened to the shipment, it was sent by boat in stead of airmail.

Niek · Answer

FINALLY got my EZ-B after 5,5 weeks

Niek · Answer

Yes! it works, if you have a 3 pin ping))) sensor, you need to make the trigger and response port the same and it will work with 250 delay!

robotmaker · Answer

on the maxsonar you can hook it up as HC-SR04 OR SRF04 USING ECHO AND TRIGGER ON THE MAXSONAR TRIGGER IS RX PIN AND ECHO IS THE PW PIN no conversion is needed like in analog mode,also analog mode jumps aroung alot and not always steady and its great for robot eyes dual ultrasonic sensors dont fit well in most robotic toys eyes but a single transmitt and receive ultrasonic sonar can

another thing about using the maxsonar it using very low current ,not like the hc-sr04 or parallax does ,2ma compare to 30-35ma on parallax ping so battery will last a lot longer cost it lower too $25 compare to $30
