TDK i3 Edge-AI Enabled Wireless Sensor Module Instruction Manual

i3 Micro Module
Edge-AI enabled Wireless Sensor Module
for Condition based Monitoring
Oct. 2023

Overview

In many industrial applications, there is a need to prevent anomalies in machinery and equipment to minimize downtime.
Productivity and efficiency can be improved by predicting problems, rather than reacting only after breakdowns have occurred.
TDK i3 Micro Module – Ultracompact, battery-powered wireless multi-sensor module – was designed to facilitate this type of predictive maintenance in any kind of industrial applications.
It achieves vibration sensing at almost any desired location without physical constraints such as wiring. This accelerates the prediction of anomalies in machinery and equipment, enabling an ideal implementation of Condition based Monitoring (CbM).
Monitoring through real-time visualized empirical equipment data instead of relying on manpower and scheduled maintenance, understanding the health of machinery and equipment to help extend uptime, and minimizing downtime by preventing unexpected failures – all contribute to establishing an ideal predictive maintenance system.
