It’s a wireless tri-axial sensor for continuous vibration monitoring of structures like bridges, tunnels, railways, and buildings — helping detect vibration events, assess structural health, and ensure safety compliance.
The sensor uses a 3-axis MEMS accelerometer with an edge algorithm that identifies threshold breaches based on Law/PPV and frequency, ensuring only critical vibration data is reported.
It supports LoRaWAN and 4G LTE, enabling long-range, low-power communication — up to 10 km coverage using repeaters, even in underground or remote environments.
With its ultra-low-power design, the replaceable battery lasts up to 1.5 years under normal operation, ensuring reliable long-term deployment.
Yes. It’s fully compatible with Worldsensing’s Loadsensing network, allowing seamless integration with CMT platforms, dashboards, and digital twin systems for real-time visualization and analytics.
It can be installed on bridges, tunnels, buildings, industrial machinery, and construction sites, including underground or hard-to-reach locations, providing continuous vibration insights for diverse infrastructure projects.
