G Link
Description

Combining MEMS accelerometers with MicroStrain's award-winning Micro Datalogging Transceiver systems, G-Link® is a high speed, triaxial accelerometer node, designed to operate as part of an integrated wireless sensor network system.

Featuring 2 KHz sweep rates, combined with 2 Mbytes of flash memory, these little nodes pack a lot of power in a small package. Every node in the wireless network is assigned a unique 16 bit address, so a single host transceiver can address thousands of multichannel sensor nodes.

The bi-directional RF communications link can trigger a sample to be logged from 70 meters, or request real-time data to be transmitted to the host PC for data acquisition/analysis. The frequency agile system enables simultaneous real-time streaming from up to 16 nodes in the 2.4 GHz range.

Available in 2g or 10g range, these small, fast, wireless accelerometers can be used to monitor tilt and vibration in a wide range of machines and structures.

A Software Development Kit is available, which includes fullycommented source code and a compiled executable for: Microsoft® C++ 6.0, Microsoft® Visual Studio C++ .NET 7.1, Microsoft® VB 6.0, Microsoft® VB.NET 2003, Microsoft® VB.NET 2005 and LabVIEW® 7.1.
