2.2 Temperature measurement
TBSCS1 3D accelerometer and magnetometer module provides an embedded temperature sensor. It shall be
used for getting temperature indication rather than an precise measurement like with a PT1000.
Supported measurement commands:
aM1! aMC1! aC1! aCC1! internal temperature
The measurement unit is C by default, but it can be configured to F through extended SDI-12 command
XSTUC!/XSTUF!.
2.3 Hard-iron and soft-iron compensation measurement
While performing the hard-iron and soft-iron measurements, M2! returns the calculated hard-iron offsets
(Mag_X_HI, Mag_Y_HI, Mag_Z_HI in mGauss) and soft-iron scaling factor (Mag_X_SI, Mag_Y_SI, Mag_Z_SI).
Supported measurement commands:
aM2! aMC2! aC2! aCC2! Mag_X_HI, Mag_Y_HI, Mag_Z_HI, Mag_X_SI, Mag_Y_SI, Mag_Z_SI
These corrections can be reset to their default values with extended SDI-12 command XSHS,0!.
2.4 Magnetic declination compensation
The heading is measured vs the magnetic North. If the user needs to get the heading aligned with the true North
or simply desires to set a custom reference direction, an offset can be applied to the final calculation through the
extended command aXSMD,sn!.
Valid offset ranges from -90 to +90 degrees.
