Fluid Level Detector Circuit PCB


Posted on Feb 5, 2014

Here is the circuit of a fluid level indicator which shows each level in meaningful English letters. The circuit presented here using seven segment display to display the letter E for empty, L for low, H for half, A for above average, and F for full tank. The circuit is comprised of CMOS IC`s CD4001, CD4055 and a 7 segment display driver. The dec
