Abstract:
A control and monitoring system for determining at least the temperature of a cooktop positioned above at least one controllable energy source and having a utensil disposed on the cooktop, the control and monitoring system comprising: at least one detector for detecting infrared radiation and generating a detector signal representative of at least the temperature at least one of the cooktop and the utensil; at least one filter connected to the at least one detector for limiting the infrared radiation into at least one predetermined infrared radiation wavelength range comprising at least one of a first infrared wavelength range representative of infrared radiation from the cooktop and a second infrared wavelength range representative of infrared radiation from the utensil, the detector signal being generated from the detected infrared radiation in the predetermined infrared radiation wavelength range; and at least one processor connected to the at least one detector for determining at least one parameter based on at least the at least one detector signal.
