Subtitle: A practical guide for factories, OEMs, and industrial automation teams to implement low-cost, high-impact condition monitoring using sensors, DSP, and edge AI. A New Reality: Machines Fail Silently Before They Break Every rotating machine—pumps, motors, gearboxes, HVAC blowers, spindle drives—emits a signature. Before a bearing cracks, vibrations increase. Before a gearbox fails, harmonics shift. Before a pump leaks, noise spectra change. Traditionally, condition mo
