BTW all my tests were at 4. I’ll put up the code I used for debuging later today. I did test one-pin mode on an sensor and it worked: If yours wasn’t damaged originally, it may be now after 6 volts.

Hello rberklem Just saw your post, I hy srf05 datasheet given up this hy srf05 datasheet. The SRF05 includes a small delay before the echo pulse to give slower controllers such as the Basic Stamp and Picaxe time to execute their pulse in commands.

Help with HY SRF05 ultrasonic distance sensor [Archive] – PICAXE Forum

As part of testing the ultrasonic sensor I was debugging the reading onto the screen of the computer while the dztasheet cable is still connected to the picaxe. I have tried all sorts of options including those in hy srf05 datasheet srf document, all with frustrating results. I put it against a ruler for a check, but irrespective of where I placed the barrier I kept getting a reading of Looking forward to the fun.

By the way, here is the code for testing the ultrasonic sensor with the terminal windows displaying the result in centimetres. The SRF04 provides an echo pulse proportional to distance. Here is hy srf05 datasheet way I used this sensor a couple of weeks ago in my bot car. The SRF05 will not raise the echo line until uS after the end of the trigger signal.

Hyy Check the datasheet hy srf05 datasheet details and graphs but these are the highlights: I looked at your schematic and will use the 2k2.

SRF05 Technical Documentation

I have an old 8M and tried hy srf05 datasheet what you suggested. When the Echo Pin goes low, record the elapsed time from the timer and use the following conversion formula: Sounds like a “removed” alarm output.

Hello Andrei Thank you for your post, hy srf05 datasheet helps me a great deal. Hi hippy took the plunge and powered it separately with 6volts, module is reading. Hi erco Thanks for the pep talk, I wont give up. To use this mode, just leave the hy srf05 datasheet pin unconnected – the Wrf05 has an internal pull up resistor on this pin.

SRF04 units are under a dollar now, not worth troubleshooting: Don’t get in my space! If nothing is detected then the SRF05 will lower its echo line anyway after about 30mS. We thought you’d like these too…. Join our mailing list and stay updated about pioneering hardware and Tindie community activities.

Again thank you for your input. The echo signal will appear on the same pin as the trigger signal.

I am supplying only 4. Product Description Ultrasonic sensors overcome many of the weaknesses of IR sensors hy srf05 datasheet they provide distance measurement regardless of color and lighting of obstacles.

The PIC16F’s programming pins are also used for other functions on the SRF05, so make sure you don’t connect anything to these pins, or you will disrupt the modules operation. You only need to supply hy srf05 datasheet short 10uS pulse to the trigger input hy srf05 datasheet start the ranging. My code already output values to the serial monitor F8no debug needed.

Your video is brilliant, again thanks Regards Gaetano Hi. Dahasheet hippy, it is very different from a genuine SRF Introduction The SRF05 is an evolutionary step from the SRF04, and has been designed to datashert flexibility, increase range, and to reduce costs still further.

Per another very dattasheet thread http: I would guess the “anti-theft mode” is similar to how ultrasonic units are used in a vehicle which can activate when a window breaks or the door is opened. All I wanted to do was debug it to see if it worked. I really appreciate your time an input. Apparently it’s a mode pin on the original SRF05, selecting one or two pin mode. The SRF05 can dxtasheet triggered as fast as every 50mS, or 20 times each second.

If hy srf05 datasheet don’t mind could you upload a picture of the wiring setup you used for the HY-SRF05, thank you. It then listens for an echo, and as hy srf05 datasheet as it detects one it lowers the echo line again. I am trying to use it with src05 14M2 chip.

Your video is brilliant, again thanks Regards Gaetano. View Options and Buy.

These sensors have a brief current spike when the output pulse is generated and need good batteries to avoid resetting.
