Thanks Pete,

Definitely. I'd be very happy to help you out with a setup. I need to install my Zigbee Gateway and my Digi Cellular router in my bus; hopefully, in the next couple of weeks I can get this done. Then I'll be able to buy a pay-as-you-go M2M data plan. This will allow us to get a feel for the kind of bandwidth required.

So you'd need:

1) Arduino Uno and a Temperature sensor (we can use this to monitor much more, including voltage): $25
2) XBee Pro Series 2 (digital radio): $40,
3) DiGi ConnectPort X2 (ZigBee Gateway): $100,
4) CDMA/GSM Cellular Router: $250 to $300, and a
5) Cellular Data Plan ((buy-as-you-go): $4 to $8 per month

So around $400 will do it. I emphasize that the data plan is a plan that would be useful for just our SAN application. The cellular router is a very capable device that you can hang an 802.11 wireless access point off of and use to connect all your onboard computers to the internet. If you'd like to do this then you'd buy an appropriate data plan.

I'd be thrilled to help you out Pete!

Many thanks David,
I'm on the road now and the Pomeranian has a serious heart defect and is extremely temperature sensitive..... this will give me the "freedom" of worry I want when we site see on the next walk about out west! Way too much to see and do! BTW take your time, I know how busy you are with the family and the kids being out of school take priority!!!!!! I can always implement, even on the road!
