Connecting a Humidity and Temperature Sensor to an Intel Galileo or Edison board is not as simple as one would like; but after looking into the right forums, it is not difficult either, took us 1 day to realize.

So here we share what we learned in the process (so far).

  1. The DHT11 is a very cheap and easy to find sensor. It has great precision and it is easy to utilize.
  2. We were able to prove to ourselves that instructions provided by DinoT_Intel in the forum work in an Intel Galileo GEN 1
  3. Basically we can download the three code files as we did in our most recent experiment in GITHUB) into one single folderwhere the Sketch resides; and it will work fine. You can also create a folder “DHT” in “~/Arduino_version/libraries/” and place the two files DHT.h y DHT.cpp there (but you’ll need to reload the IDE)
  4. Our tests worked in a Galileo GEN1 perfectly using an ARDUINO IDE version [arduino-1.5.3-Intel.1.0.4] that we downloaded here.
  5. IMPORTANT: Use 7ZIP to extract the arduino IDE from the file into c: … you can download 7ZIP here.

This time we were not able to make it work in an Edison; but we’ll tell you when we get to that point.

Special thanks to @spider_kenny for his contribution of knowledge about deterministic time devices and interfaces. I think it will be the foundation we’ll use to make it work in EDISON.
