The proximity sensor is placed in proximity with the rotating shaft, facing it. Whenever the bare object is in front of the proximity sensor the reflected signal is high. NOTE: the RPM is an average ...

Mechanics RPM Measurement Tool This simple device, built using an Arduino Nano and an A3144 Hall sensor, allows you to measure the RPM (Revolutions Per Minute) of a gear. The device is straightforward ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The … ...

Non-contact sensing of a nearby object’s linear or rotary position in an electrically and mechanically harsh environment is a common system requirement. There are several ways to meet this objective, ...

Inductive position-measuring systems (IPMSs) operate on the same principle as an inductive proximity sensor. But instead of a single sensing coil, position measuring uses a multiple-coil system.
