Claim:
1. A cooking sensor system, comprising: a burner assembly; a vibration sensor assembly configured to generate a vibration signal that corresponds to vibrations of cookware situated on the burner assembly; and a processor arranged to receive the vibration signal and determine at least one of a boiling onset condition and a boil-dry condition for a liquid contained within the cookware, wherein the determination is based at least in part on (a) a conversion of the vibration signal into a vibration data set comprising vibration power versus frequency, and (b) a comparison of the vibration data set to boiling attributes of the liquid, and further wherein the boiling attributes comprise: (i) a predetermined threshold frequency, (ii) a predetermined boiling onset threshold vibration power, and (iii) a predetermined peak boiling threshold vibration power.
