1. A system comprising:
a camera;
one or more processors communicatively coupled to the camera; and
a memory including instructions that are executable by the one or more processors for causing the one or more processors to:
receive, from the camera, an image of coffee grinds produced by a coffee grinder;
analyze the image using one or more image processing techniques to determine a representative grind size for the coffee grinds;
determine a grind setting of the coffee grinder;
select a predefined reference size based on the grind setting of the coffee grinder, the predefined reference size being selected from among a plurality of predefined reference sizes corresponding to different grind settings of the coffee grinder;
determine whether the representative grind size of the coffee grinds deviates from the predefined reference size by at least a threshold amount; and
in response to determining that the representative grind size of the coffee grinds deviates from the predefined reference size by at least the threshold amount, output an instruction indicating how to calibrate the coffee grinder to more closely adhere to the predefined reference size.
