To measure geomagnetic data precisely, a measure system is described which is based on fluxgate sensor. This four-channel and 32-bit precision system which is constituted of ADC and MCU program is stable and can be used in long-term outdoors measure or indoor science research. Compared with the existing geomagnetic acquisition, the acquisition board designed by this measure has advantages of low noise, large dynamic range, low-power and multi-channel.Thoughout laboratory and field testing, the data collected by this measure have a high quality.
