Hi Werk_AG, engolling,
yes you are right. The low low power Tx unit will bring some disadvantages or compromises, but can be usefull in many cases.
And there is very good idea of your system - you can combine data from more Tx units.
Will be not usefull for everybody, but somebody will be very hapy with it.
From technical point of view :
- 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 ?
Finally, it can be battery powered in some cases. Or it will decrease dramaticaly power consumption and it will be much more easy to use solar power. I know, in Portugal there is enough sun. In our county there is ussually more then one week calm inversion weather in the winter time, without possibility to take any power from solar cells.
