Cerbo has 4 analog inputs dedicated to resistive tank sensors and 4 analog inputs dedicated to LM335 temperature sensors. The GX Tank 140 provides 4 voltage or current based tank sensors. There is no expansion for temperature inputs. These analog inputs differ only in the pull-up/down and what the input is used for in software.
The GX Tank 140 inputs could easily be retasked in software to support temperature sensors. They have a mild (150 K ohm) pull-up which should be sufficient for the LM335 temperature ICs.
For the next hardware revision of Cerbo, I propose the 8 analog inputs be modified to support resistive, voltage and current tank sensors as well as temperature sensors, then in software, you can decide how many of each you use.
