Newbie: Temperature measurements

[mackrackit]

A NEWBIE that wants to learn!!! Welcome.

http://www.rentron.com/pic.htm Has some good tutorials .

None of this is hard if you take it step by step.

Years to learn? Depends on how many hours a day you work on it. Hour or two a day and in a few weeks this project should be running.

HAVE FUN

Thank you all for those encouraging messages!

Trent,
thank you so much for your post. It seems like a very sensible and logical idea to do that. My Programmer is on the way (i hope I can do 16f628a with it) and i will get into researching each block. Are there any webpages you would recommend so I can understand those steps better?

mackrackit,
Great site thanks! i already spend a good amount of time there and am in the process of taking the whole tutorail step by step. Is it a problem that everywhere I look for entry level stuff I see 16F84? Will it be difficult for me to switch to 16f628a later?

Acetronics, thanks for the tip. It would be great to see a ready-built solution as something I could aspire to. However, after spending 1 hour (seemed like days) on the Maxim site I gave up. The site is clearly written for people who deal with electronics a lot and don't need explanations. I found several temperature elements and even some references to Time/Temperature/Event Recorders but they were nowhere to be seen as products...

Paul,
while your posts are still over my head I understand the need for something that gives me the time. After all I need a timestamp to record a timeline. Thank you for the tip about the memory. I will probably first build one without external memory and then a couple with. That would enable me longer logging times, no? A week would be great.
But more about that later, once I got the basics down...

Not a problem. You can do more with the other chips, but that is all part of the learning curve. Basically all of the micro chips are the same.16F, 18F The same as a Chevy and a Rolls. You can drive one, you can drive the other. Might have to look around a bit for the wiper control, but still the same.

Bet I get slammed for this analogy.

Hi, Budda

You have here ... as a starter kit !!!

Seems DS 1615 and 1616 ( 1615 + 3 Analog recording channels ...) have been stopped ...

Now, there is the 1Wire "thermochron" you can interface straight to the Computer !!!

PS: ya ... their site is not so easy to browse ....
