logging of seperate power rail

cellectronic Sep 26, 2023 01:42 PM

Hi All,

We have a CR1000 based solar powered weather station at a remote location , This station forwards data to our server at hourly intervals.

The communications for the CR1000 is via a LAN and wireless communications radio link .

The communication link is powered from a seperate power supply which is also solar powered and isolated from the CR1000 power.

What I wish to do is log the voltage on the secondary power supply for the communications ( I am already doing this for the Weather station PSU).

which would be the best way to achieve this , any ideas would be appreciated.

VDIV10:1   With the voltage divider, you can read up to 50VDC on the CR1000.

Also connect the ground connections between the two power supplies if not using a common ground already.
