Programmable electronic circuit to process a halleffect signal for use in a liquid level sensor

摘要

A system and method for measuring liquid levels is provided. The system includes a sensing device disposed within an enclosure comprising a liquid therein, the sensing device generates a raw signal indicative of a surface level of the liquid in the enclosure; and an programmable device circuit in signal communication with the sensing device, the programmable device circuit samples and processes the raw signal producing a variation in voltage at an output of the programmable device circuit, the variation in voltage emulates a variable resistor at the output of the programmable device circuit.
