  • The sequential logic is interesting to me, but I don’t know what Q in the diagrams stands for. Pretty basic I expect, but hard to follow without it.

  • If I read the data sheet correctly, the rating is per output.

  • Can I place multiple DHT22s on the same wire and address them individually?
    I know Maxim can handle this and I’d like to minimize the pins used for this on my Arduino as I’d like to put as many as 10 on my system, but I don’t see where it states this capability for this version of 1-wire.

  • I think it would be neat to hook this up to Nagios to get TXT and Twitter notifications of service outages. If anyone takes this project on, please share.
