problem with DHT11 returning 21 bits instead of 41 ...

Using Arduino Sensors

Hi,

Something strange happened when i used your code for replacing the PulseIn() command ...
I got these results :

112,116,112,120,112,120,112,120,112,120,112,120,112,120,116,112,112,120,112,120,112,120,112,120,112,120,112,120,112,120,112,120,112,120,112,120,112,120,112,120,120,516

Surely, i couldn't use them because they was very inacurate (max value : 124 ; min value : 112) ...
I then realised that in your code the command "analogRead" was used, and i changed it to "digitalRead" which was more appropriate, and then TAAADAAA !!!! miracle !!!!

I could then obtain the total message of 41 bits which looked like this :

I modded the DHT11 library v0.4 of George Hadjikyriacou to reflect the changes.

Thank you for your help, now the lib is working greatly =]

PS : When the lib will be finalised, i'll post it right here on this post.

By the way, as it seems thath the "PulseIn()" command has a bug, is there a way to report the bug to the DEV TEAM of the arduino ?
