Data Sheet The WSDA® -Base-104 USB Base Station operates as an integral part of MicroStrain® mXRS™ Wireless Sensor Networks. It provides seamless communication between a host PC, single board computer or microcontroller, and single or multiple remote wireless nodes. Coupled with MicroStrain® Node Commander® software, the WSDA® -Base-104 supports configuration of the wireless nodes including discovery, initialization, radio frequency, sample rate, reading/writing to node EEPROM, calibrating nodes'sensors, managing the nodes'batteries including sleep, wake and cycle power, and upgrading the nodes' The WSDA® -Base-104 supports all data acquisition sessions between wireless nodes and host computers including Synchronized Sampling (both Continuous and Burst modes), Armed Datalogging, Datalogging, Streaming and Legacy Low Duty Cycle. Features & Benefits Support for hundreds of simultaneously sampling wireless sensor nodes Node to node synchronization of+/- 32 microseconds Ultra-stable on-board precision timing reference of +/- 3 ppm over industrial temperature range Extended wireless communication range to 2 km Condition 1 based monitoring of machines and aircraft Health monitoring of civil structures and vehicles Embedded OEM sensing systems Smart structures and materials Experimental test and measurement Robotics and machine automation Vibration and acoustic noise testing Sports performance and sports medicine analysis Distributed security networks System Overview At the heart of MicroStrain's mXRS™ Wireless Sensor Networks is the WSDA® -Base, which uses our exclusive beaconing protocols to synchronize precision timekeepers embedded within each sensor node in the network. The WSDA® -Base also coordinates data collection from all sensor nodes. Users can easily program each node on the scalable network for simultaneous, periodic, or burst mode sampling with our Node Commander® software, which automatically configures network radio communications to maximize the aggregate sample rate.
