audioPMD

The Predictive Maintenance Device designed for monitoring and anomaly detection in wind turbine components. Installed inside the nacelle the audioPMD uses sound as a sensor to alert early when the machinery doesn't sound right. 

FEATURES

• All-in-one design, integrating: Nvidia Jetson with 8-channel audio streamer, video cameras, PLC RS485/NMEA2000, LTE/5G router, LoRa router / transmitter options, Out-of-Band management GSM module and accessory sensor boards;
• Multi-pipeline design: dedicated Machine Vision and Machine Audio autonomous, self-learning edgeServer runtime pipelines that detect anomalies and raise alerts ahead of time;
• User-friendly interface for anomaly classification labeling and configuration (on edge and cloud);
• Heavy-duty passive cooled design, silent operation;
• IP67 rated, outdoor use in harsh environments;
• Lifetime warranty with marine.audiopmd.com subscription plan;

Advanced gas monitoring - 5-Gas Sensor:
Simultaneously monitors carbon monoxide, methane, ethanol, propane, butane, hydrogen, hydrogen sulfide, and ammonia - critical for complex industrial environments.

Standard embedded sensor is the MiCS-5524 - a robust MEMS sensor for indoor carbon monoxide and natural gas leakage detection; suitable also for indoor air quality monitoring; breath checker and early fire detection.

Detectable gases
• Carbon monoxide | CO | 1 –1000ppm    
• Ethanol | C2H5OH | 10 –500ppm 
• Hydrogen | H2 | 1 –1000ppm          
• Ammonia | NH3 | 1 –500ppm
• Methane | CH4 | >1000ppm
