Sensor Noise

Short definition
Sensor noise is unwanted variation in a measurement that does not represent the actual behaviour of the measured physical quantity.

Why does sensor noise occur?
Electronics, vibration, temperature, electromagnetic interference, installation conditions, environmental effects...

Why does it matter?
Noise can affect monitoring, control, statistics, anomaly detection and AI models.

Example
An ultrasonic sensor installed on industrial machinery may report rapidly changing distances even when the measured object has barely moved.

How can sensor noise be reduced?
Brief explanation of filtering/smoothing and why simply averaging everything may be problematic.

How OWASmooth approaches it
Then only 2–3 sentences, not sales copy:

OWASmooth processes sensor measurements in real time to suppress unwanted variations while preserving relevant changes and events in the signal.
