In Topic: DS18B20 Readings

29 April 2013 - 12:11 PM

Ziggurat29, I am sorry I just realized I posted this in two different places on the forum. I found a solution to the problem thanks to another forum member. There was a data type issue in the code I was using from http://www.tinyclr.c...hare/entry/438. They were using ushort instead of short during the conversion/casting. So I would get correct readings down to 32 deg F  or 0 deg C but then once it tried to read below that it would  show readings in the 7k range this is all because ushort only allows positive values. Thanks for the attempt in lending a hand, I appreciate it!

The code change did the trick, thank you so much for the help! I will let the author of that article know about the issue i experienced. Thanks again!

Purchased some 4.7k? resistors at lunch and am going to make the code changes tonight. Hopefully we get some desirable results. Thanks for the help!

The sensor is powered by the 5V ND output that is jumped from the ND to the Bread board. I was not able to get a reading from the sensor until i used a resistor.  I am not sure how many ohms the one I am using at the moment is, as I am a new to all of this and have only what came in my starter kit. 

 

I am using the same code that Brad used in his blog post here (http://bradsduino.bl...vices-with.html) with just a slight modification to output the serial number along with the temp. 

 

 

Thanks for the help.
