Description

I am only a beginner at this. So would be very happy for anyone to point out problem with the design. This would be very helpful. Thanks

The unit is design to be connected to 7 float similar to the one in the image,(attach file) on the block Bottom right. As the water rises the LED bar on the left indicates the level. Power & Buzzer indicator. With the rotary switch top right to can set the level the buzzer sound indicated on the LED on the right side.

This unit could be used in a water tank or basement sump. Any comment would be great I am still unsure if it will work as have not built it. (planning to) any help to make it better power wise etc would be much appreciated.
