Abstract: An induction cooktop includes a glass-ceramic substrate defining a cooking surface and an underside opposite the cooking surface and an induction heating coil positioned beneath the underside of the cooking surface. The induction cooktop further includes an infrared sensor directed toward the underside of the glass-ceramic substrate and outputting a first temperature reading of the glass-ceramic substrate during heating of a cooking article positioned on the cooking surface using the induction heating coil and a far-infrared sensor directed through the glass-ceramic substrate and outputting a second temperature reading of the cooking article and the glass-ceramic substrate. A controller determines a temperature of the cooking article using the first temperature reading from the infrared sensor and the second temperature reading from the far-infrared sensor.
