The accelerometer is a 3-axis digital-output linear MEMS sensor that includes a sensing

element and an IC interface capable of taking information from the sensing element and

providing the measured acceleration signals to external applications through an I2C/SPI

serial interface. The LIS3LV02DL has a user-selectable full scale of ±2 g, ±6 g and is

capable of measuring acceleration data over a bandwidth of 640 Hz for all axes. The device

bandwidth may be selected according to application requirements.

The SPZB250 is a ready-to-use ZigBee® module for OEM use. It integrates the SN250

ZigBee® system-on-chip (SoC) with an external oscillator, a balun filter and an antenna.

The SN250 SoC design integrates a full-featured 802.15.4 radio with a 16-bit processor. It is

designed to run the EmberZNet ZigBee® protocol stack from Ember Corp., and can be fully

reprogrammed to run custom applications.

The MotionBee™ modules also integrate a SIF connector, allowing interfacing with the

Ember development kit for firmware loading and debugging. Finally, the module integrates

two LEDs, 1 power connector, 1 power switch, a reset button and a commissioning button.

ZigBee® dongle

Based on the SPZB250, the ZigBee® dongle (“dongle” in the rest of the document) is a

module with a USB stick form-factor. It provides a cost-effective method of adding ZigBee®

wireless connectivity to any device which employs USB. The dongle can be programmed

using the SIF connector integrated in the board. When connected, the dongle is powered

through the USB and it can be used to transfer data to the connected operator for data

analysis, storage and computation. The dongle uses a USB controller from FTDI Ltd. to

communicate with the host computer.

The main components of the dongle are represented in Figure 4.
