This series of analogue modules is a low cost way to acquire fluxgate conditioning circuits for medium-volume autopilots and other robotics which need Earth's field guidance.
This is a range of high-precision analogue modules aimed at sensitive differential magnetometry. The modules are supplied with sensors with field-nulling windings to negate the Earth's field and so permit very high gains which the high signal-to-noise fluxgate technology permits. Ideal for sub-soil detection.
The autonnic range of digital output OEM compass modules contain software to convert the output of 2-axis magnetometer - such as one of the A407X series - to heading. Software includes auto-calibration and a choice of formatting and speeds.
