Ad590

Posts: 46,084
I have done some research on the AD590 and now I have some
questions. I would like to use the AD590 but does anyone have an
opinion between the the flat pack as opposed to the TO-52? If I use
the standard RCtime that is listed in the BS2 manual, what other
commands do I have to use to read farenheight?
Thanks,
Chris

The flat pack is usually hard to get and expensive. The AD590
(different accuracy grades) are often available surplus.
Alternatives with much the same characteristics are the AD592
(TO92--used in Applied Sensors), the TMP17 (SO8-can make a thin
probe) and the LM334 (TO92 cheap but requires extra resistor).

Thanks for the reply. If I use the code that's listed on the link
you gave me along with the AD590 will it esentially be plug and
play? Also, is it possible to get farenheight from that code?
Thanks,
Chris

It's "plug and play" except for the fact that you have to do a simple
one-point calibration to get best results. The URL shows how to do
that. The calibration accounts for the tolerance of the AD590
itself as well as component variations in the capacitor and the Stamp
RCtime threshold.
I corrected a couple of typos in the URL and put in the conversion to
degrees Fahrenheit. The first result is in Kelvin, so
Fahrenheit = Kelvin * 9/5 - 460
The basic RCtime routine there captures the temperature to 1 degree
Kelvin, or about 2 degrees Fahrenheit. The extended version gets to
1 degree Fahrenheit, and that is pushing it for RCtime, which
requires good circuit layout to minimize noise.

I hooked up the 590 like it says on your website but it doesn't work
correctly. My Kelvin temp is about 60 degrees too low. Even with
the max number for cal it's still too low. The pins aren't marked
on the sensor but I am relatively sure I have it hooked up
correctly. I'm not sure what else to try, can you shed any light on
this?
Thanks,

Do you have a meter that can measure current on the order of 2
milliamp full scale? Measure the current from your AD590...
+9 volts
|AD590|
|millamp-meter|----common
It doesn't have to be 9 volts--anything from 5 to 15 volts should do
with no change in the milliamp reading.
At room temperature, the reading should be around 300 microamps.
More specifically, the reading in microamps should equal the
temperature in Kelvin. Can you do that?

I have a meter that can read microamps, I try that today. One thing
I did notice, I have two .1uf caps but each one, when installed,
will display completely (70 kelvin) different temps. Both are not
polarized but one is blue and one is yellow, monolithic I think.
The blue one displays what I think is just about the correct temp
and the yellow one, at room temp, will display 245 kelvin.
Thanks again for the reply,
Chris

Update: I said before that I get different reading with two kinds
of .1uf caps. One cap gives me 284 kelvin at room temp and the
other gives me 236 kelvin. I have a uA meter hooked up to it and at
68 degrees I am getting about 299 uA. I checked that reading with
both caps and it's the same. Just to make sure, do I insert "kal
var word" into that code you listed?
either initially nor as a function of temperature. They might have
the Z5U ceramic, which is +80%/-20% tolerance. Other bypass types
could be +/- 10%. But for best results, get ahold of a film
capacitor, like mylar or pps film, which could be +/- 2%.
The calibration step should account for all the errors unless they
are out of the bounds that the math can work with. Use components
with low drift with temperature. The vagaries of the RCtime circuit
limit the accuracy of this approach to about 2 Kelvin.

I am a student of Mechanical Engineering at University of South
Florida.I have a limited background of electronics and through a
friend of mine working on BAsic Stamps, I learnt about this group.
I am working in the field of Robotics and am making a robot arm
gripper. I need to control three DC gearmotors and ensure the work in
a synchronised fashion using a Motor Mind B. I had a few questions as
to how to do it.
1. Is it possible to control three DC Motors using a single Motor
Mind?
2.The operating voltage for each motor is 0.29 A and a peak voltage
is about 0.65 A. Is this voltage too high for the Motor Mind B?
3. How do I connect the leads of three motors to the Motor Mind B and
how do I connect it to the Basic Stamp?
I tried running one motor using a sample program as provided in the
S3 manual. It worked fine. Now I am trying to run a single motor in a
reversible manner using a centre-off toggle switch. What values do I
specify in the program? I mean do I specify a -1,0,1 values for
Reverse-Stop-Forward or do I need a 1,0,2 Values for the same?
I understand that this being my first email and am asking too many
questions. And its quite likely I may be too vague and unspecific
about my queries If someone can provide me some help, I can finish my
projects really quickly.

Do you have a meter that can measure current on the order of 2

+9 volts
|AD590|
|millamp-meter|----common
It doesn't have to be 9 volts--anything from 5 to 15 volts should do
with no change in the milliamp reading.
At room temperature, the reading should be around 300 microamps.
More specifically, the reading in microamps should equal the
temperature in Kelvin. Can you do that?

1) No...MMB's are designed to only control one motor at a time...running more than one motor in parallel or series will most likely damage the MMB.
2) Do you mean your Currents are .29 and .65 Amps? If so..No, the MMB can easily handle this.
3) You will have to figure this out yourself (VERY easy to do at http://www.solutionscubed.com/ and at http://www.parallax.com/
Looks like your project may take a little while longer..hope this helps
