The datasheet shows how the am2302 works. It is a 1 wire device which actually can be pretty easy to program. I did some of this with dallas sensors on an arduino a long time ago. (dallas uses a different format).
Any language that can access the gpio ports on the BBB can be used. My preference for applications that are not time critical is python because C gives me hives. (okay just kidding, I just like python for easy stuff). Adafruit has a tutorial for raspberry pi in python. You should be able to adapt it easily to the BBB. http://learn.adafruit.com/dht-humidity-sensing-on-raspberry-pi-with-gdocs-logging On Fri, Feb 21, 2014 at 11:45 AM, <[email protected]> wrote: > I have a Adsong dht22 (am2302) sensor that I would like to use on BBB.
