Accelerometer - Libelium Waspmote Technical Manual

7.1.2. Accelerometer

Waspmote has a built in acceleration sensor LIS3331LDH STMicroelectronics which informs the mote of acceleration variations
experienced on each one of the 3 axes (X,Y,Z).
The integration of this sensor allows the measurement of acceleration on the 3 axes (X,Y,Z), establishing 4 kind of events: Free
Fall, inertial wake up, 6D movement and 6D position which are explained in the Interruptions Programming Guide.
Figure: Accelerometer
The LIS331DLH has dynamically user selectable full scales of ±2g/±4g/±8g and it is capable of measuring accelerations with
output data rates from 0.5 Hz to 1 kHz.
The device features ultra low-power operational modes that allow advanced power saving and smart sleep to wake-up functions.
The accelerometer has 7 power modes, the output data rate (ODR) will depend on the power mode selected. The power modes
and output data rates are shown in this table:
