dht-11 temperature sensor problems

Mon May 26, 2014 6:24 pm

Hi there :)
I've been using this tutorial to get my dht-11 temperature sensor working: http://blogs.sequoiainc.com/blogs/raspb ... re-monitor
The attached file shows the output. As you can see, most of the outputs don't work, and when it does, sometimes it gives random readings(ie at the top it reads 4 degrees).
I've connected it with a 10K pullup between data and 3v3.
Any help/advice much appreciated.
Thanks in advance.

I tried to get the DHT-11 with the Pi about a year ago, failed and moved on. I can get it to work easily on an Arduino but no luck with the Pi. Would love to know if this is possible.

Good Luck!

For the similar DHT-22. If you can program you will be able to make the minor changes required.
