Convert Battery Voltage to Analog

Other Hardware General Electronics
1

I have a remote location project where I am transmitting ip webcam via cell signal and this system is powered by 4 12volt batteries and solar panel and regulator. The system is deep in a canyon that doesn't contain cell coverage so a relay has been setup to the top of the canyon. I'm unable to currently monitor battery voltage remotely and am concerned about the battery voltage dropping below operational levels. I also have a timer wired into the system in case voltage is too low I can cut power to the camera at night to conserve.
I also have a Sutron Satlink data collection platform at the site that is monitoring river levels and precipitation. This system has it's own battery and solar panel and transmits SDI-12 data via satellite.

SO, I'm wondering if there is a way to convert the web cam battery data and transmit it via an anolog port in the Sutron Satlink using the satellite setup?

Thanks

If you have the SatLink2-V2 with a free analog port, it should be trivial to measure the voltage of a battery. If the battery voltage to be measured is greater than 5V, you will need a voltage divider to reduce it to within the range of 0-5V. There must be a common ground connection, of course.

If for some reason a direct connection is not possible or desirable, then you can't use the analog port and will need some other means for the two systems to communicate.

INSUFFICIENT DATA .

Post the voltage level to be measured (+/- 15%)
What does this have to do with arduinos ?
