Abstract
A monitoring device performs a method of detecting a need for maintenance of an exercise machine comprising a time-of-flight, ToF, sensor. The method comprises obtaining a measurement signal from the ToF sensor at a predefined operating condition of the exercise machine. Based on the measurement signal, the method determines a measured distance between the ToF sensor and a reflective element in the exercise machine. The measured distance has been found to be responsive to accumulation of deposits on the ToF sensor and is thus evaluated by the method to detect a need for cleaning. The method thereby enables preventive maintenance.
