A hubodometer for attachment to a wheel hub comprising an outer housing enclosing equipment for measuring distance travelled based on the wheel hub's number of revolutions, and a NFC-based communications link for transmitting to an external unit data related to the measured distance and for receiving operational data such as the diameter of the vehicle's wheel, and the position of the hub to which the hubodometer is attached. The equipment comprises a first electronic assembly conjoined with the outer housing and a second assembly comprising an anti-rotation pendulum provided with two permanent magnets of opposing polarities, the positions of which subtend an angle smaller than 180 degrees. The first electronic assembly comprises a bipolar Hall sensor moving in a circular path that traverses North and South fields of the magnets, whose output signal is a rectangular wave in which different mark-to-space ratios are associated with forward or reverse travel direction.
A hubodometer for measuring distance traveled by vehicles of various types based on a wheel rotations counting device that counts rotations of a wheel of the vehicle, the hubodometer comprising a rigid protective cover and a revolvable base provided with means for attachment to a wheel hub, said hubodometer also comprising a non-magnetic disc-shaped pendulum holding a pair of permanent magnets arranged to subtend an angle of less than 180 degrees, and being provided with means for exchanging information with an external unit via an NFC electromagnetic link, said magnets being oriented with opposing polarities and an electronic assembly is provided which comprises a bipolar Hall sensor connected to a processor as well as other electronic components, mounted on at least one printed circuit board, wherein said bipolar Hall sensor output is an asymmetrical rectangular wave transitioning between the logical levels “0” and “1”, said wave being produced by the traversal of said bipolar Hall sensor through the opposite-polarity magnetic fields of said magnets, a transition between said logical “0” and “1” levels being conditional on sequential passage of said Hall sensor through the magnetic fields of opposite polarities, ether north to south or South to North, and said processor operating in hibernation in an absence of signals from said bipolar Hall sensor.
