Tips: How Does Capacitive Level Sensor Work?

A capacitive water level sensor operates based on changes in capacitance to determine fluid levels. It typically consists of two electrodes—one exposed to the fluid and the other insulated.  When submerged in water, the capacitance between these electrodes varies with the water level. Capacitance is influenced by the dielectric constant of the material between the electrodes, which changes as water fills or drains. As the fluid level rises, capacitance increases, and vice versa. The sensor measures these capacitance variations and converts them into corresponding water level readings.
