Two part question: How does one configure for Fahrenheit printout and how

does one add a second DHT11 to the sketch? At the moment I have the

sketch configured for one DHT11.

Thank you for the tutorial, it worked on the first go.

I will do that. Thanks for the code and the help it was appreciated.

With the help of the people of Arduino forums I've got this project working for my setup. faintfuzzies.ca:8080 I'll keep it up and available until tomorrow. The code is here it is still not perfect as I can't get it to run more than 30 minutes before it start spewing garbage and then crapping out.:

With some help I've got the code to work sort of... If you go to the webserver faintfuzzies.ca:8080 and let the code run 3 or 4 minutes will see that things go a bit haywire. If you get nothing it just means that the webserver has crashed again. I've tested it both with Chrome and Firefox with similar results.

Yes I do have DHT library installed and I managed to fix the code up and got the DHT part working...

now I've new sets of errors.

working2_2DHT.ino: In function ‘void sendTempToNetwork(EthernetClient)’:

working2_2DHT.ino:65:23: error: expected primary-expression before ‘.’ token

working2_2DHT.ino:70:23: error: expected primary-expression before ‘.’ token

working2_2DHT.ino:76:32: error: expected primary-expression before ‘.’ token

working2_2DHT.ino:76:51: error: expected primary-expression before ‘.’ token

I believe the first error has to do with line 53 of your code, but I'm not sure what is wrong.

Tried this code with my Arduino Uno and Arduino Ethernet Shield.

So far I've got these errors:

How DO I Add DHT11 library .. I tried Changing DHT22 to DHT11 in source code But it doesnt work. its comming up with error saying ;

'dht' does not name type

DCT22_test:7: error: 'dht' does not name a type

DCT22_test.ino: In function 'void sendTempToNetwork(EthernetClient)':

DCT22_test:62: error: 'DHT' was not declared in this scope

I am trying to use DHT11 in same code above !

Thank you
