thanks once again most especially to our presenter, sir randy for the whole week class in giving us wisdom of another technology we are looking for.

thanks to digikey and design news for continuing education as required for PDH Collection...hoping a PDH VALUE be mailed...thanks again...

going back to another class topic of semester 3...

it's about to end now, thanks for the presentation that gave wisdom in today's smart sensor application sir randy...i am now on slide 19...

great! i am now on slide 15 of today's smart sensors...

i am now on slide 2 for day 5 presentation of today's smart sensors...

i am now downloading the presentation slides of day 5 class lesson of sir randy...

here i am again for day 5 presentation of sir randy...thanks again to all...

Very informative lecture

Iron

@Chuck - hall effect positioning sensors... (e.g. AMS)

Iron

Great to have access to the recorded sessions!

Iron

Missed the live lecture

Iron

Taking the class offline

Iron

Randy - thank you for an interesting set of classes and the additional links more ifromation on gyroscopic sensors would be interesting.

Iron

last catch-up on this topic

Iron

Good class - thanks for archiving it.  The first course in sensors coupled with this one ties a lot together.  That said, would like to wrap it up and tie the bow on with a detailed design walkthrough, most of the pieces which are already here now and not in any insufficient otherwise.

Gas sensing /particulate sensing / chemical sensing are other areas to touch on:

      exhaust sensor similar to Oxygen sensor in catalytic converter that senses

      soil sensor (temp/H2O/chemicals) for farm and research monitoring, water and fertilizer guidance

      smoke / CO sensors for example

thanks randy a another great series of discussion

no i am not working on anything related to that

 

seems like alot of new sensors are availible

I am interested alot in humity senors

Thanks for the course Randy.

Iron

Thank youfor archiving this course

Iron

Thank you very much Randy and all! Outstanding week!

That's going to do it for today and this week for me.

Thanks to everyone.

so it's modern perspective, almost all sensors integreated with ARM cores now?

ARM cores target many application processors but the sensor-specific MCUs nad DSPs are usually not ARM based.
Blogger

Randy:

Lots to think about now. Thank you kindly.

Iron

TMP06 difference -- see user manual...

http://www.ti.com/lit/ug/sbou107/sbou107.pdf

Typically less than 1/2 meter... not a simple calc.

Iron

I have a question, do you usually use sensors like accelerometer and gyroscope with integrated sensor fusion software, or do you develop such software yourself? And are there combinations with integrated SF software for any combination of accelerometer, gyroscope and magnetometer? Thanks.

 
The sensor suppliers usually offer their own sensor fusion software but there are sensor fusion software suppliers whose products work with the different sensors that are available. Companies like Movea, Xsens and others offer just the software.
Blogger

Does TMP006 thermopile sensor need point to measured object? and how far away?

The range is not jumping out from the data sheet for me. Perhaps it will for you:

http://www.ti.com/lit/ds/symlink/tmp006.pdf

Blogger

DSP guruis can pint you at several packages that help you analyze the sensor data -- forgot about this till someone mentioned Matlab:

http://www.dspguru.com/dsp/links/matlab-clones

Lots more than Matlab clones there.

Iron

For statistical analysis of sensor data

http://www.r-project.org/

One suggestion... (free as well)

Iron

Where does the Tire Pressure Monitoring System get its power from?

 
A battery supplies today's units but there is a lot of activity to use energy harvesting.
Blogger

Gnu Ocatve:

http://www.gnu.org/software/octave/

Download from there

Iron

You can also Use GNU Octave -- Matlab like and "R" for Statistical analysis

Iron

What does the recevier end of the TPMS look like?

The frequencies are in the Industrial, Scientific, and Medical frequency bands and handled in a dashboard mounted unit, sometimes in concuntion with the door lock system.
Blogger

@apdobaj I understand and feel for you purchased most of my tools myself.. Mathcad and some third party low cost simulation programs, tried to get Labview but they cut the part of the package I wanted from the order.

 

Good luck

Iron

I just noticed the links you included in the "notes" section of each of the slides. Good to have. Thanks Randy.

 
Thanks for pointing that out. Today is the only day I haven't specifically mentioned them.
Blogger

Topic for future sensor sessions: Biometric sensors, Security for data, GPS, Software optimisation, Debugging and Troubleshooting. Development / Simulation tools.

@Randy - what tools do you use for signal analysis? Matlab, others? How good are the vendor supported tools?

 
Matlab could be one choice. National Instruments has great capability in the signal area, too. Vendor tools are key to designs in so they tend to be pretty good and well worth the effort to use them.
Blogger

@gwp2 Ha! It's a one man show for me right now, got a copy of Matlab with simulink off craig's list the other day for 80 bucks.

Iron

I just noticed the links you included in the "notes" section of each of the slides. Good to have. Thanks Randy.

Iron

@ JSP: update rate depends on the number of processors working on the GPS signal

Iron

Thanks, very interesting

Iron

apdobaj must be nice to work at a company that buys tools..... 

Iron

also, interesting topic for me would be sensors used for biometrics.

Iron

TPMS uses same principle of communication as RFID

Iron

Thanks great week!

Iron

@Randy - what tools do you use for signal analysis? Matlab, others? How good are the vendor supported tools?

Iron

Other topic's I know there are many but since you asked ...... blank.

Great Seminar.

Iron

I 2nd DaveWR:

"A seminar on GPS and GPS modules would be interesting especially if it covered WAAS and GLONAS"

including the MT3329 - how do they get that 10Hz update rate ?

Iron

I would like to seee about GPS and image sensors.

Iron

Thanks Randy and Chuck. The was a great presentation.

Iron

Thank you Randy and Chuck,

Iron

thank you, this week was my first course here, very interesting.

Iron

RF short distance M2M for single sensors

Iron

What does the recevier end of the TPMS look like?

Iron

Thanks Randy and Chuck, for a great session and week.

Iron

Randy and Chuck, thank you so much. Have a nice weekend.

Iron

Randy, thank you for the great lectures that you have provided.

Thank you Chuck

Iron

Thank you Randy & Chuck

Iron

Thank You Randy and Chuck.

Iron

Thanks Randy and Chuck!

Iron

Many thanks Randy and Chuck!! I enjoyed this 5 days full of useful info

Iron

How do these smart sensors compare in price to traditional sensors? And how much development effort is needed to integrate smart sensors into a design; i.e. are there special design considerations?

Iron

may be some kind of sensors need embedded encryption, for better safety

Iron

Many thanks Randy and Chuck - always very interesting.

Iron

if able to use wirebonding (die on board) can get much smaller

Iron

Reference board designs and available firmware/drivers are always a big plus. Just as important or more as size, performance and price.

Iron

That's the last time we let the ice cream man in our sessions.

Blogger

Coldfire is a 32 bit MCU of Freescale and is total different with 32 bit ARM.

 

Iron

That's that icecream Randy.

Iron

2-axis MEMS provided a roll-rate gyro.

Iron

Not purely in software

Iron

Security. They have a problem last year that Bad Guys Hack the Tire Preasure Data and Fake the other car that they have a Low Preaure on their Tires, then they follow you until you stop and check your tires, then you know what Bad Guys do.

Iron

also, i think that sensor fusion algorithms would be a good topic for some future course.

Iron

slightly confusing it's - 32-bit also as  ARM

Iron

I have a question, do you usually use sensors like accelerometer and gyroscope with integrated sensor fusion software, or do you develop such software yourself? And are there combinations with integrated SF software for any combination of accelerometer, gyroscope and magnetometer? Thanks.

Iron

Coldfire is not an ARM licensed architecture IP.

Iron

so it's modern perspective, almost all sensors integreated with ARM cores now?

Iron

TPMS, I think, has a battery.  It should be able to benefit from energy harvesting to extend the life.

Iron

Does TMP006 thermopile sensor need point to measured object? and how far away?

 

Iron

RF output from a loadcell when the info is called for.

Iron

Am I working on soething like that? Sensing required by law? Yes. ;-)

Iron

Where does the Tire Pressure Monitoring System get its power from?

Iron

The BGA style packages make prototyping difficult.  Having SOIC or even QFN styles available really helps.  And they are perfectly fine for non-space constrained designs and low-volume.

Iron

I'd like an icecream.

Iron

I get audio for a few seconds

Iron

Chuck, Smaller size and power are always opening new doors but as always cost and reliability must be factored in.  I am not working on anything at this time though but I will keep it in mind.  It's always good to know what is out there.

Iron

It did sound like the ice  cream man.

Blogger

hall effect, magnetic field would be interesting

Iron

i didn't have the chance to use such small sensor yet.

Iron

The ice cream man is in town

Iron

The small size makes it tough to mount with my gorilla paws.

Iron

Today's list is OK, for future sessions: biometric sensors for variety of medical devices.

A seminar on GPS and GPS modules would be interesting especially if it covered WAAS and GLONAS

Iron

Is it cost effective?

Iron

connection issue, no sound

Iron

Your content just is my interesting.

Iron

Someone mentioned hygrometer, but GPS would be interesting

Iron

Magnetic field, hall effect

Iron

i think the list covers most of what we need

Iron
