Can't compile Humidity sketch 2.0 .. What DHT library do I need?
-
@chuckconnors - BMP180 or Bmp280 for example.

Those appear to be atmospheric pressure sensors. Looking for humidity sensors other than the DHT11/DHT22.

Hello,
DHT22 is already much better than DHT11 which I think is complete garbage: wild variations in both temp and humidity between sensors, too unprecise and it's getting worse with time.
I heave read somewhere (sorry don't remember where but it was a guy testing a lot of temp/humidity sensors) that the best one for humidity is BME280. It has also atmospheric pressure and temperature (but is not really good for temp) like BMP180/280.
The Si7020 like on the sensebender micro seems pretty good too.Just don't expect the same price level :D

I'm dead in the water with the same issue. Downloading the lib from the location above yielded the same result.

@r-nox did you download the library from MySensors or did you follow the link in the readme and download the upstream version of the library? Only the former will work.
I can't tell what I'm using anymore. Been at it all afternoon installing and un installing. I think I'm using these now (https://github.com/mysensors/MySensorsArduinoExamples/tree/master/libraries/DHT).
Where do I start please?

I really like mysensors.org, but I've always had difficulties with the site organization. In my opinion, is not intuitive at all, although it has a great and appealing theme.
Well, maybe it shouldn't, but this sets me back when trying to build anything... I know this excellent initiative for a couple of years now, and from time to time I try to do something but I end up de-motivated because it takes too long to find simple answers/solutions. At the moment, I have nothing built although I have all the equipment I need, including SenserBenders. Yes, frustrating like r-nox commented 2 years ago.
Anyway, my point is: For the ones looking for a library that makes this DHT sketch work, mysensors have compiled a set of libraries that include this DHT.h and many others. Just go to https://www.mysensors.org/about/arduino#optional---install-external-mysensors-examples (yes, the name is not intuitive, maybe the keyword library would make it more obvious?), or jump directly to here and follow the standard library instructions. It took me two hours to find this, hope it saves time for future followers of mysensors like myself.
Good luck!
