The ZSTAR3 development tool contains one accelerometer transmitter boards and one USB receiver node. A ZSTAR3 system can accommodate upto 16 accelerometer transmitter boards, connected through an RF ZigBee 2.4GHz communication to a single USB node connected to a PC. The accelerometer boards measured acceleration in 3-axes using either a digital or analog sensor. The sensor sensitivity is defined by the selected accelerometer. The USB node is part of the ZSTAR and ZSTAR2 design, reprogrammed with dedicated SW supporting multiple nodes.
The ZSTAR3 development tool offers a new PC software interface that shows all the basic accelerometers functions with enhanced features. It also has added accelerometer functions, as well as digital accelerometer configuration capability to help customers learn more about the digital accelerometer products and the various modes of operation as well as providing recommendation for the optimal settings for the various modes.
