Water indicator Circuit to measure the level of any liquid

This document describes a simple water level indicator circuit using a NE555 timer IC. The circuit uses two probes - one at the bottom water level and one at the top water level. When the bottom probe is uncovered, the 555 output goes high, triggering a relay that powers a motor. When the top probe is covered, a transistor resets the 555, turning the motor off. The circuit provides an automatic way to measure and control water levels to reduce waste and electricity consumption.Read less
