Wireless 2.4 GHz G-Link®

Product catalog summary

Introduction
G-Link® is a high-speed, triaxial accelerometer node designed for integration into wireless sensor networks. It combines MEMS accelerometers with MicroStrain’s Micro Datalogging Transceiver systems, offering 2 KHz sweep rates and 2 Mbytes of flash memory. Each node has a unique 16-bit address, allowing a single host transceiver to manage thousands of nodes. The system supports real-time data transmission and logging from up to 70 meters, with simultaneous streaming from up to 16 nodes in the 2.4 GHz range. Available in 2g or 10g ranges, these accelerometers are suitable for monitoring tilt and vibration in various applications.

Catalog excerpts

Combining MEMS accelerometers with MicroStrainΒs 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 fl ash 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.
