Patent attributes
A capacitive fluid level sensor is provided for receiving data indicative of the level of fluid remaining in a fluid container. In various embodiments, the capacitive fluid level sensor may be spaced below and a distance away from the fluid container to be measured, and may comprise a fluid level sensor and an ambient sensor, wherein the fluid level sensor and the ambient sensor are coplanar. In various embodiments, the ambient sensor may be spaced a distance away from the fluid level sensor, such that electric fields generated by the fluid level sensor and the ambient sensor, respectively, do not overlap. Based at least in part on capacitance levels determined by the fluid level sensor and the ambient sensor, the fluid level sensor may generate data indicative of the fluid level in at least a portion of the fluid container located above the fluid level sensor.
