I want to do some remote monitoring sending temperature data from several locations throughout the house ending up to a remote linux system over the internet.
I'd like to use ( nanoV3 $15,
Leonardo $23(no headers), Uno is $30, Netduino2 $35 ) .
First issue is radioing data from multiple tiny nodes to a internet node (a wireless router) inexpensively. I don't want to involve a local host (concentrator) like a PC.
Does anyone have any experience interfacing with USB WiFI dongles less than $10 like: "Mini 150Mbps USB WiFi Wireless N LAN Network Adapter 802.11n/g/b " http://www.ebay.com/itm/281079713722?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
or "USB 2.0 WIRELESS N ADAPTER 150M Cordless ETHERNET WiFi CARD With Antenna" USB 2.0 54Mbps 802.11g Wifi Wireless LAN Adapter http://www.ebay.com/itm/USB-2-0-WIRELESS-N-ADAPTER-150M-Cordless-ETHERNET-WiFi-CARD-With-Antenna-/390563900103?pt=US_Video_Cables_Adapters&hash=item5aef6c2ac7
Second issue is MAC, IP address, netmask, gateway "hard configuration" seems simplest. For example just "burning" 64:b9:e8:d1:ea:nn, 192.168.1.nn, 255.255.255.0 , 192.168.1.1 where nn is unique for each tiny-node.
Third issue protocol: Seems that syslog is easiest service since it is a send only, UDP protocol.
Your suggestions and experience are appreciated.
