A capacitance probe is a type of sensor used to measure the level of liquids or solids by detecting changes in capacitance. It operates on the principle that the capacitance of a capacitor changes when the dielectric constant of the material between its plates changes, which occurs when the level of a substance (like liquid or solid) rises or falls.
