2.3 Sensors

XDK110 is equipped with a multitude of sensors on board, which makes it an ideal tool for
application development for the Internet of Things.
This documentation refers to the datasheets of the sensors for a deeper understanding of the
components. It is, however, vital to understand that sensor performance will be limited by the
application hardware. As an example, the temperature range of most sensors will be -40 to +85 °C
in the datasheet, while the XDK is only specified for a usage between -20 and +60 °C due to
physical and safety limits of the battery. Also, sensor accuracy is generally higher in the sensor
datasheet than it can be expected from the target device, since the assembly process and
mechanical stress of the board influence the performance of any sensor. The absolute maximum
ratings of the key parameters are stated for each sensor. For more details, please refer to the
respective sensor datasheet.

2.3.1 BMM150: Three-Axis Geomagnetic Sensor

The BMM150 is a standalone geomagnetic sensor for consumer market applications. It allows
measurements of the magnetic field in three perpendicular axes. Based on Bosch's proprietary
FlipCore technology, performance and features of BMM150 are carefully tuned and perfectly match
the demanding requirements of all three-axis mobile applications such as electronic compass,
navigation or augmented reality.
