Wireless Vibration Meter

SHAKEdot

Feature and Application

Introduction

SHAKEdot is a vibration meter featuring LTE-M and NB-IoT wireless communication and provides tri-axial vibration and temperature measurements. It is powered by two 18650 lithium batteries and supports 5‒18 VDC charging, enabling long-term measurement, data logging, and upload to the dot Cloud web service. A built-in 32 GB microSD card provides sufficient storage capacity for over one million data records. SHAKEdot integrates a Peak Particle Velocity (PPV) trigger function compliant with DIN 4150-3 and BS 7385-2 standards. It is designed for monitoring vibration impacts on structural safety, including construction vibration monitoring for urban civil engineering projects, bridge structures, high-tech industrial facilities, and historical buildings.

Applications

Key Features

LTE-M and NB-IoT wireless transmission

MQTT Protocol

Real-time monitoring enabled via LTE-M / NB-IoT and dot cloud integration.

Supports MQTT for versatile data acquisition and integration.

Low Power Consumption

Cloud-based Software for Real-time Trigger Monitoring

The device uses two 18650 lithium batteries and transmits data once per hour. When no trigger events occur, it provides an operating life of at least 3 months at RSSI < 15, and up to 6 months at RSSI ≥ 15.

When vibration exceeds the set threshold, data is instantly sent to the cloud for 24/7 real-time monitoring and early warning.
