Analog Devices offers the ADI OtoSense Smart Motor Sensor (SMS), an AI-based hardware and software product that monitors industrial electric motors in real time to detect signs of mechanical or electrical failure before they cause unplanned downtime. The product is available to industrial customers across multiple sectors globally.

The ADI OtoSense SMS attaches to 3-phase induction motors up to 500 kW and continuously collects data from on-board vibration, magnetic field, and temperature sensors. The device transmits 2.4-second sensor samples to the ADI OtoSense Cloud platform, where proprietary AI algorithms build a unique baseline model for each motor during an initial learning period. After that period, the cloud platform compares incoming sensor data to the baseline to detect anomalies and predict nine categories of mechanical and electrical faults, presenting results via a web dashboard and mobile app. OtoSense technology originated with ADI's 2018 acquisition of OtoSense, a company specializing in AI-driven sound and vibration recognition.
