Issue #082 [New/open] - Integration of DHT11 Humidity sensors

Posted by chof258

I have programmed a sensor class for the DHT11 humidity sensor and probably other versions of the DHTXX family:

The sensor is utilizing a new C extension for python, to communicate with the hardware which I have included into the native section of the code.

It was tested on a raspberry pi model 2 and works fine

I also updated the sensor module and webpage to handle humidity data. Please feel free to try it and integrate it into your software

Kind regards

Christian

Thanks you very much, but there is few issues :

WiringPi code is under LGPL license, incompatible with Apache WebIOPi licence http://www.apache.org/legal/resolved.html#category-x

So you should use gpio.c:pulseTS or inspire from it instead. But all GPIO native code is planned to be removed later.

A humidity sensor (HYT221) will be added shortly, and will provide a different mapping from your proposal
