| 摘要 |
The invention relates to a home automation device comprising at least one detector (30) of the position of an object being monitored, comprising a housing, a magnetometer (34) which supplies signals representative of the instantaneous intensity value for the local magnetic field, a unit (31) for processing the signals of the magnetometer (34), a memory (32) comprising a predetermined calibration value for the intensity of the magnetic field, characterised in that the processing unit (31) is programmed so as to calculate a constant value on the basis of said calibration value and on the basis of a plurality of intensity values supplied by the magnetometer for a plurality of positions of the housing, and to replace said calibration value in the memory (32) with said constant value. |
