Having developed some ideas surrounding the Sensors, the design for the Monitoring Station needs to be considered, in order to allow them to interface. The system will use RTC to synchronise transmission between nodes in a sequential order, with the furthest away first, adding data to the packet one by one until it reaches the Monitoring Station. This means all the unit has to do is receive the raw data, process it and then interface with the internet and also the user. Based on that I have produced a block diagram of the system operation.

So in essence the hardware will be similar, however a MCU will also be incorporated to interface with the LCD and HTTP stack.
