Hello!

I just want to share my BSEE graduation project here with you guys.

Hope it helps someone...

Your questions & comments are highly welcomed.


For completeness sake, I uploaded Appendix C, which contains selected some useful Data Sheets related directly to the project.

ultrasonic sensors distance measurement

Anyone implemented parts fo this excellent project ?

I plan to implement, but I am facing problems in finding ultrasonic sensors in my area.

Do you know good distributors for them in any area?

Best regards,
Rodrigo

There are ultrasound sensors that work underwater, you should ask in your local store.

ultrasonic distance meter using pic

A cool project but ultrasonic is affected very much by temperature, any temperature compensation for it?

ultrasonic pic

Hi all,
I have read all of your replies involving ultrasonics, ultrasonics are tricky one to handle because speed of sound varies with temperature, humidity and if in any other medium then so a compensation is necessary the difference between ordinary and underwater ultrasonics is of frequency.
any one of you worked on Doppler's shift in ultrasonics.
I am working on a project in which i have to analyse the frequency distortion of an ultrasonic wave when passed through different gemstones it is beneficial in testing the quality of those stones


if any one has ideas please share.

Dear Saeed,

I neglected the effects of Doppler's shift in my project. I thought it was beyond the main scope of the undergraduate project.

If you have done or come by any related analysis, please post/upload.

Thanks for your comment...

ultrasound distance pic

I tried to build the project but a deeper look into the schematics seems to have some problems: the 2 diodes in reverse polarity are connected in parallel with the ultrasonic sensor, meaning that the voltage across the sensor could never exceed 0.6V. Then how can the 40KHz signal be applied to drive the transmission? May be I am missing something??
