In Topic: Is there a moisture sensor to put in the ground?
01 July 2011 - 04:03 AM
JonnyBoats,
Thanks for the insight. So I guess reading the moisture content of something physical is slightly more of a challenge than originally thought. And that's because i can't find a sensor that will do that for me... But really isn't it the same idea as a pentiometer? One prong receiving electricity, another for it to exit, and one in the middle to read what's moving across the other two?

Can anyone show a simple working example of the XmlReader reading an attribute from an element? Otherwise I’ll move on to using strings instead. I don’t mind that the features aren’t available. The struggle is the limited resources in finding out if they are. Does a guiding rule exist when working with Netduinos (or other Micro Controllers) that could help determine if specific Assemblies, namespaces, classes and functions will not functioning as expected? Coming from a Web Dev. background I’m finding that I’m wrestling with the limited features of the micro framework. I like the refined and fresh approach of tackling the issues but I feel like I’m finding dead ends at every turn. I’m sure it’s just the learning curve but any help is appreciated. That’s why I like the forums. So, if anyone could answer the two questions above, Thanks in advance!

Thanks for the good feedback. Though I still don't seem to be able to get this to work for me. With the code below I'm receiving this error when I hit the XmlReader. Any ideas?

The system.xml class does not appear to have any options that can return attributes of an xml element. If no options exist, what's the alternative?
