Thermistor Help

01 June 2011 - 08:48 PM

I have a TTC 103 thermistor
The specs:

TTC Series

R25 = 10000 ohms
B25/50 = 4050
Disipation = 4.5mW/degC
Tolerance of R25 = 5-10-15

Can someone show me how to get the A/B/C constants needed for the Steinhart-Hart Thermistor formula from the data sheet?

Or is there a better method using the thermistor?

System.Math problem

01 June 2011 - 04:33 PM

I'm probably doing something utterly stupid. Using the micro framework... The System.Math.ABS will only take a type int...it seems to have only that one overload. Same with System.Math.Round... will take a double, but not a second parameter to specify the number of places to round to. Anyone else seen this?

Beginner Question and Hello!

27 April 2011 - 03:04 PM

First off hello all! Great forum you guys have here. A little background: I'm not a programmer by trade, but have written some VB.Net winforms apps reading serial devices etc. On the electronics front, I can use a meter and have a comfortable relationship with a breadboard. I've got my Net+, done the simple LED/Button/Voltage Divider projects. Mostly have a handle on the basics of these. So, to help me out you might need to "dumb down" your answers a little more than you are used to. ;) I make beer. My project goal is connect 6 thermistors to the Net+ and map the temperature profile in my mash tun throughout a mash. An app running on my PC would connect to the Net+ vis ethernet and collect that temperature data to trend/log/whatever. The main point being a learning Net+ project that provides some useful results. That ethernet connection (sockets I guess) is where I need some patient help. I ran the webserverhello world example and that was pretty cool, but that really doesn't fit my project. Maybe there is already an example of how to do this here, but everything I've found so far seems to be interested in http only. Maybe that will be a next step for me, but right now I'm having enough trouble fighting C# syntax... I don't need to add something else I completely don't get. :unsure: Thanks ahead of time! Gordon
