14 / 20 | Revision: 0 | DS161
Sensor Specifications
Please read the following table for sensor specifications.
Feature
Detail
Measurement Ranges
±5 mT and ±130 mT
3 channels, for the measurement of magnetic
field in X, Y and Z direction
Note:
The ±5mT range has an absolute
measurement span of ±4.6mT to ±5.2mT. This is
unique to each sensor and cannot be adjusted.
Accuracy
±5% of reading
Resolution
