Following Device (circuit) to indicate the water level of two different tanks.
N MOSFET is used as sensor and 5 LEDs as output to indicate water levels.
Switches S1,S2,S3,S4,S5 are coming form tank one; and S6,S7,S8,S9,S10 are coming form tank two.
Separator S11 is used to switch between tank 1 and tank 2.
I think Separator is not enough to switch between two tanks which produces Mix/Misleading results.
I can not figure out, how to isolate both tank's output using Separator and diodes. I can understand there must be diodes to block current flow kindly help..
Update: added 2 diodes between S1 and R1, and also between S6 and R1. still did not get what it suppose to do.
