Introduction

When we think of artificial intelligence, massive servers and powerful GPUs come to mind. However, an industrial transmitter or vibration sensor in the field doesn't have access to such computational power. This is where TinyML (Tiny Machine Learning) comes into play. TinyML is the art of running machine learning models on microcontrollers (MCUs) with just a few kilobytes of memory. This technology transforms industrial sensors from simple data collectors into intelligent devices that understand what they see.

What Does TinyML Change in Sensors?

Traditional sensors collect and transmit data. A smart sensor with TinyML:

  1. Local Decision Making: Analyzes data on-device without sending it to the cloud. This means zero-latency response times measured in milliseconds.
  2. Bandwidth Savings: Transmits data only when an abnormal condition (failure, leak, etc.) is detected. This reduces energy and communication costs for IoT systems.
  3. Privacy and Security: Cybersecurity risks are minimized since critical data is processed without leaving the device.

Industrial Application Examples

  • Anomaly Detection: Can detect a previously unseen failure mode from a motor's vibration within seconds.
  • Intelligent Filtering: Uses deep learning models instead of classical filters to distinguish between noise and real data (e.g., tank sloshing vs. actual fill level changes).
  • Audio Analysis: Sound-based analysis systems that can determine which bearing needs lubrication from the sounds machines make in a factory.

Amazeng and the AI-Powered Future

At Amazeng, we're making our data acquisition devices "Edge AI" compatible.

  • The 24-bit high-resolution data from our ZMA Data Acquisition devices provides the highest quality training material for TinyML models.
  • The modern MCU infrastructure we use in our embedded system architecture enables libraries like TensorFlow Lite Micro and Edge Impulse to run on our devices.

Conclusion

TinyML is a silent revolution that increases the "IQ" of industrial sensors. In the factories of the future, devices won't just be connected to each other; each will have its own small artificial intelligence in its area of responsibility.
