Water Level Sensor Readings Not Changing with Water Level Variations

[admin]

A8Sv2 have 4 channel analog input port: 2CH is 0-5v 2CH is 4-20mA total can use for 4 pcs water level sensor.
you can chose 0-5v or 4-20mA output version.

Thanks! all clear. 

I've a main controller running HA at home. I want to manage water level sensor, pumps, solenoids and some perimeter sensors in remote locations (25m, 75m from main the board). I understand an extension board close the sensors make sense... Could you advice what controller would you use? Maybe RS485 (only 2 wires, long distances) fits for the case.

Best regards

pumps, solenoids is OUTPUT device, 25M and 75M is ok.
if you use long distance, suggest chose "current" type of analog sensor, such as "4-20mA" version, it can work with hundreds meters , no problem.
