- with arduino mini pro it's possible to get mikro Amps quiscent current after easy changes. The firmware in Tx unit is short, not to often to download new one - can be done via FTDI adapter.
- RF via RFM69HW ?
- And what about idea to do in Tx unit sensor measurement and also some data aquisition and lower the transmit rate by this way ?

Hi mrazou,

Sorry to say, but what you are proposing imply almost a completely new system... new TX, new software on TX and RX, months of testing, etc, etc, and most important, it will break compatibility with oldest systems.

I did not expect you designing a new TX board.  Wink  I just wanted to say that a new PCB has to be made to realize mrazoun's ideas.
I know exactly how long it took to get reasonable results measuring the snow height Smile

As I already told, i first have to bring my system outside and the next project will be a foto webcam.


Best regards,
