The invention provides a dual thermometer system for the measurement and display of temperature data taken at two separate locations within an oven. In one aspect, the invention provides an elongated probe connected with a flexible electronic cable. The probe houses two temperature sensors—one for sensing internal food temperature, one for sensing inside oven air temperature. The sensors are space apart within the probe such that the one sensor can be positioned substantially within a food item and the other sensor can positioned substantially outside of the food item and within the oven. Signals from the sensors are relayed from the probe and through the cable; external electronics may attach to the cable to acquire the signals and display associated temperatures. In another aspect, signals from temperature sensors are relayed from the probe and through the cable to a first wireless termination. The first wireless termination wirelessly relays signals from the probe to a second wireless termination coupled to module electronics, to acquire the wireless signals and to display associated temperatures. In operation, the probe is inserted into food within an operating oven, such that one of the sensors senses food temperature and such that the other of the sensors senses oven air temperature; the cable extends from the probe and through the door of the oven; the module electronics may be attached to a convenient location in the kitchen, usually near to the oven, to display temperatures from the probe.

A digital frying pan provides temperature and/or food doneness information associated with food cooked within the pan. A thermal sensor coupled with the pan senses temperature and generates corresponding signals, and processing electronics coupled with the sensor convert the signals to data for display on a LCD. A warning buzzer or LED warns the user of completed cooking. The frying pan may be programmed to desired food types or personal temperatures or food doneness options. The invention also provides a remote sensing food doneness system for remotely viewing and then determining food temperature and/or food doneness. The remote system uses thermal imaging optics and thermal sensing techniques to remotely sense food temperature. Preferably a second optical element images the food onto a CCD to display an image of the food to a user. The system is mounted by a user who views the CCD to ensure appropriate placement in line of sight from the food. A warning is generated by the system to indicate food doneness or desired temperature.
