I'm completely new with Arduino and would appreciate some guidance on how to fit the different Arduino components.
Basically I would build 2 types of Arduinos:
Subscriber station: This Arduino would collect information from an IR sensor and send it to the Base Station via Xbee. Should I get an Arduino FIO and an XBee module? is that enough?
Base station (May be a YUN Arduino board with the GSM and Xbee modules...). This would collect information from the Subscriber stations and send it to the internet via 3G, so I thought a YUN board with the xbee module and the GSM Shield would be enough.
Do you think my approach is correct? Do I need more or different parts for my idea? Any hints?
