Cooking aid with a floatable, hermetically sealed body

A system for detecting or determining a cooking state of a product that is heatable in a fluid, the system comprising:

• a floatable, hermetically sealed body comprising:
• at least one temperature sensor (20) accommodated in the floatable, hermetically sealed body (1, 1a) and adapted and arranged to measure an ambient temperature of the floatable, hermetically sealed body (1, 1a);
• an electric power source (30);
• a first sound generator;
• and
• an electronic component with a transmission unit or a radio interface (50) with an antenna (52) for transmitting the ambient temperature measured by the at least one temperature sensor (20) and an electronic assembly with a model-forming arithmetic unit (11);
• wherein the radio interface is a bidirectional radio unit, and
• wherein a center of gravity of the floatable, hermetically sealed body (1, 1a) is selected and arranged such that, when the floatable, hermetically sealed body floats in a fluid volume immersed to a certain extent, the antenna (52) will be located above a fluid line or a fluid surface;
• a smart device comprising:
• a radio interface for receiving signals transmitted from the electronic component and the electronic assembly of the floatable, hermetically sealed body (1, 1a);
• an electronic arithmetic unit with a memory having stored therein at least one model for a product with at least one predetermined cooking point for the product;
• a processor for comparing data received from the floatable, hermetically sealed body (1, 1a) with the at least one model stored in the memory;
• and
• a second sound generator to output a signal perceptible by a user, when the at least one predetermined cooking point has been reached,
• wherein the bidirectional radio unit or the model-forming arithmetic unit automatically switch to a low-power mode with a power consumption of less than 5 μA if they are not active for a predetermined period, and communication between the smart device and the floatable, hermetically sealed body is only established if data or parameters are transmitted or exchanged,
• wherein the first sound generator of the floatable, hermetical sealed body is used to wake up the bidirectional radio unit or the model-forming arithmetic unit from the low-power mode.
