Water-Level Sensor Uses Hysteresis: 08/21/00 Electronic Design - Ideas for Design / A low-voltage electronic circuit that senses upper and lower water levels is often used for alarms and sump-pump activation. Since an electronic sensor has no moving mechanical parts, it eliminates problems with corrosion and wear and tear.
