The electronic compass has at least one magnetic field sensor (4) connected to an electronic circuit. The electronic circuit which follows the sensor is comprised of at least one operational amplifier (8), one voltage stabilizer (20), one temperature compensation device and one analogue-digital converter (9). The changes of value of the magnetic field sensor (4) will thus be amplified and transformed into digital and/or analogue signals of a certain amplitude. The signals are exploited in digital and/or optical and/or acoustical form. It is thus possible to use a microprocessor. |
