Systems and methods for determining fluid aging

A method performed by a sensing device, comprising:

• receiving radiating light upon interacting with a portion of a fluid stored in a receptacle;
• generating an output signal proportional to amount of the radiating light being absorbed by the portion of the fluid;
• determining an absorption spectrum associated with the portion of the fluid based at least on the output signal, wherein the absorption spectrum is indicative of variation of absorption associated with the portion of the fluid across a plurality of wavelengths;
• and
• determining a rate of aging based on the absorption spectrum.

A system comprising:

• a receptacle configured to store a portion of a fluid;
• and
• a sensing device disposed within the receptacle, the sensing device comprising:
• a housing,
• at least one radiating light source disposed within the housing, the at least one radiating light source configured to emit radiating light of a plurality of wavelengths through the portion of the fluid in the receptacle,
• at least one sensor configured to receive the radiating light upon interacting with the portion of the fluid in the receptacle and generate an output signal proportional to the amount of the radiating light being absorbed by the portion of the fluid, and
• a control circuitry communicably coupled to the at least one sensor and the at least one radiating light source, the control circuitry configured, at least in part, to:
• receive the output signal from the at least one sensor,
• determine an absorption spectrum associated with the portion of the fluid based at least on the output signal, wherein the absorption spectrum is indicative of variation of absorption associated with the portion of the fluid across a plurality of wavelengths, and
• determine a rate of aging based on the absorption spectrum.
