VIII.2.2 Running as part of WiRobot System

When using the DTA5102 with the WiRobot system, user can simply connect the module to the tilt

sensor module connector on the PMS5005 controller board and the PMS5005 built-in sensor device

driver will take care of the data acquisition. Users can simply call a function offered by the WiRobot

SDK software on PC (requires Microsoft platform) or send a data request packet (platform

independent) to obtain the data.

VIII.2.3 Running as a General Purpose Tilt and Acceleration Sensor Module

When using the DTA5102 with the third party controller, the power supply and the input/output

signals should be connected properly (please refer to Section VIII.3). The controller can get the tilt

and acceleration data via an analog to digital converter. The value of the angle or the acceleration can

be calculated according to the equations in Section VIII.1.

For premium performance, several cautions need to be taken into account when operating the system:

. The power supply voltage should be 5 VDC nominal.

. The length of the cable connecting the DTA5102 and controller should be as short as possible.

. The DTA5102 module and the controller should not be in a high current path.

. If using switching power supply, be aware of the switching frequency may interfere with the

DTA5102 module.
