Hi Coding Smackdown,
It's possible to download the source of this project?
Thanks,
Ludo
As far as source code, I'm going to try and load it up on to codeplex this week. Issue with loading up here is that the file size is too big and I'd have to upload multiple posts and If I update it, you wouldn't have the latest.
But I'll definitely update this post once I get it up on codeplex. In the meantime, if you need it you can send me a message via the forums with your email and I'll send it to you.

I took a little time this afternoon and put the entire project up on codeplex you can find source code, schematic and eventually documentation at http://diybrewerytem...r.codeplex.com/
Enjoy!

#21242 Total Newbie Temperature Project

My temp readings are all over the place. Can someone please double check my setup?
I experienced the same thing. You are probably experiencing some noise from the Ethernet interface.
There is another thread in the forum that discusses the issue in some depth.
http://forums.netdui...ading-accuracy/
It is best to hook a .1uF capacitor between 3.3V and Ground to help drop some of the noise. If that doesn't work add a 1mH inductor between the ARef port and 3.3V.
I still had a lot of noise from the senors so I ended up performing 100 reads of the port and then averaging the reading:
int totalReads = 0;
for(int x = 1; x < 100; x++)
{
totalReads += Port.Read();
Thread.Sleep(10);
}
float reading = totalReads / 100;
This seems to work pretty good and is pretty fast for normal monitoring. It may not be the best performance wise, but you can vary the number of reads until you get a good smooth value back.
BTW: Are the two outer leads of your sensor actually hooked to anything? Your circuit looks strange since the two side rails on my breadboard do not have any connection to the inner holes. Try moving the pins over to the first set of holes that your leads are connected to and see if that makes a difference. Take a look at the breadboard diagram I did of my circuit here http://forums.netdui...erature-logger/ the TMP36 is pretty much pin compatible with the LM35.
Cheers!

got my netduino today, but can't look at it until Thursday (homework and a major release at work). Im sorry im such a newbie, but from the tutorials Ive looked at I was going to feed my sensors from the 3.3v output on the netdiuno, is this not what i should be using to power it?
Also if i were to power LED's from the netduino, which size resistor do i need to step down the 3.3v port? 1/2 watt 68Ohm? Anyone know of a good tutorial link for doing basic things with LEDs?
Thanks!
I've got several TMP36 sensors running off of the 3.3V supply. I think if you were going to say multiplex a lot of sensors then you might want to look into a different power source, but you should be OK.
If you want a good tutorial that covers LEDs check out the Netduino for Beginners post in the General Discussion area, its really good.
I'm finishing up a temperature monitoring project for my walk-in fermenter that has a web based interface. Once I have it all complete I'll post it to the forum to give you some ideas.
Cheers

#37387 OnInterrupt firing multiple times
Posted by Coding Smackdown on 18 October 2012 - 01:30 PM in Netduino 2 (and Netduino 1)
public static void EngageHeaterButton_OnInterrupt(uint data1, uint data2, DateTime time) { if (engageHeaterButtonLastPushed.AddMilliseconds(200) > time) return; // button press state received in data2 // 0 = open, 1 = pressed if (data2 == 1) { PinManagement.heaterEngaged = true; } _displayHelper.DisplayText("Heater|Engaged"); engageHeaterButtonLastPushed = time; }
Hope this helps you out.
