Problems solved by technology
The disadvantage is that the sensors are mostly located at different points in the household appliance, which can lead to high inaccuracies in the measurement signal due to the sensors measuring different measurement points
The sensor nodes usually require a large installation space, so that the arrangement cannot be designed flexibly here, and in most cases there is a large distance between the actual measuring object and the sensor node and the measurement signal is correspondingly inaccurate.

Embodiment Construction
[0068] figure 1 A partial sectional view showing the adaptation of the domestic appliance according to the invention in the form of a washing machine in a non-limiting embodiment. This partial sectional view shows the part of the drum 1 where the laundry carrier 3 is arranged. The sensor node 2 with its own energy supply is arranged in the laundry carrier 3 . The sensor node 2 here has a micromechanical acceleration sensor 4 with a plurality of measuring axes and an integrated evaluation unit, and a micromechanical pressure sensor 6 with a diaphragm 5 and an integrated evaluation unit. Furthermore, the sensor node 2 also has a radio unit 7 for the wireless transmission of data to the control device, which is not shown here. The sensor node 2 is here constructed with a 3×3×0.95mm 3 Space-saving modular components of the same size. Due to the spatial proximity of the two micromechanical sensors 4 and 6 in the modular component, the two sensors detect the same measurement poi...

The invention also relates to a method for operating such a household appliance.
Description
technical field [0001] The invention relates to a household appliance with a control device and at least one sensor node comprising at least one sensor, at least one evaluation unit, a self-sufficient energy supply and an interface for wireless data communication, wherein the control The device and sensor nodes are arranged to communicate wirelessly with each other. Background technique [0002] The improvement of domestic appliances has focused on designing a more reliable and easier operation for the user as well as on a continual improvement of the processes carried out therein in terms of operating characteristics, time, energy consumption and environmental sustainability. For this, the possibility of being able to determine operation-relevant parameters at any time is absolutely essential. [0003] Sensors are usually used in domestic appliances for this purpose. The sensor can be, for example, a resistive or capacitive sensor which, for example, can determine the res...
