If you often find yourself scrambling for convenient and suitable meter, uniquegoods magnetic rpm meter is your end point. The matching Hall switch is an NPN normally open type with a diameter of 12mm. The long black wire is connected to the negative pole of the power supply. It has N/S sides, only one side can be detected. The installation distance between the Hall switch and the magnet must be within 10mm.

The long red wire is connected to the negative pole of the power supply. It is better to use shielded wire or twisted-pair wire for measuring wire. The Hall switch and magnet need to be fixed firmly during detection, otherwise the shaking of the Hall switch or magnet will cause the detection data to jump or be inaccurate.
