ZSTAR3 Accelerometer Family Expansion
Multiple wireless sensing triple-axis reference design
Overview
The ZSTAR3 system accommodates multiple
digital and analog accelerometer boards,
connected through an RF ZigBee^® 2.4 GHz
communication to a single USB node connected
to a PC. The accelerometer boards measure
acceleration in three axes using a pin compatible
digital or, optionally, an analog sensor. The
sensor sensitivity is defined by the selected
accelerometer. The USB node is part of the
ZSTAR design, equipped with dedicated software
supporting multiple nodes.
