Claim 8:
9. A method for monitoring rotation data of an object comprising:
(A) attaching a universal electronic hubodometer to a hubcap on a wheel of a vehicle, wherein the universal electronic hubodometer comprises:
an accelerometer comprising a single accelerometer sensor for measuring force in any given direction, wherein the single accelerometer sensor comprises a 3-axis digital accelerometer, and further wherein the single accelerometer sensor is disposed at an angle of 60 degrees relative to the center of the wheel, and further wherein the single accelerometer is disposed at a distance of between 5 mm and 25 mm from the center of the wheel;
a microcontroller unit (MCU), wherein the MCU comprises internal read-only memory (ROM) and random access memory (RAM), and further wherein the MCU processes data generated by the accelerometer;
a communication module, wherein the communication module wirelessly transmits any data processed by the MCU to a mobile device and wirelessly receives any data from the mobile device, and further wherein the communication module comprises a wireless Bluetooth system;
a multifunctional button disposed on a front face of the universal electronic hubodometer, wherein the multifunctional button is capable of placing the hubodometer into a Bluetooth pairing mode; and
a power supply, wherein the power supply provides power to the accelerometer, the MCU, and the communication module;
wherein the accelerometer, the MCU, the communication module, and the power supply are configured onto a printed circuit board (PCB) and disposed within an outer housing;

(B) activating the accelerometer upon detection of vibration and generating accelerometer data;
(C) allowing the MCU to collect and process the generated accelerometer data into useful data comprising revolution count, distance, velocity, and acceleration of an object, wherein the accelerometer data is collected at a frequency of 8 times per second;
(D) comparing two sequential pieces of accelerometer data by subtracting the first piece of accelerometer data from the second piece of accelerometer data;
(E) transmitting the useful data to the communication module; and
(F) wirelessly accessing the useful data via the mobile device.
