How to send messages from Ruggeduino to Windows Computer

Hello,

I am setting up an alarm system for a fish study. This will probably include a Ruggeduino to read the sensor inputs and send a message to a Windows computer which will be right next to it. There is also a wireless router mounted on the wall a couple of feet away. My objective is to send out email alerts and automatically make phone calls with the computer (and or router) to alert people about the alarm state. I do not have to describe the alarm state, I just need to have a single message that says something like "An alarm state has occured at your fish study".

Can someone please make some suggestions as to the best way to approach this project?

Thanks,

Jim
