-==== Bus ==== 
- 
-RS485 will be used as the principal bus.

-=== Sensor Nodes === 
-==== Software ==== 
- 
-In order to communicate between the nodes, the MODBUS RTU protocol will probably be used. 
- 
-=== Addressing === 
- 
-If possible, the addresses could be dinamically addressed using some discovery protocol. 
-This seems really to realize on modbus and thus, some DIP switch could allow the user to set nodes addresses. 
-Since the modbus adressing can go up to 255, a 8 input DIP switch will use 8 GPIOs.
