5 Abstract This is the era that health is inseparable from manufacturing process. No high-tech manufacturer can survive more efficiency tools. The design of the pedometer discussed in this article, utilizing a microchip 8051 to count steps with its programmable control function, and by receiving the data from the vibration of this pedometer performs its task by seamless synchronization of the counting and the vibration. The microchip 8051 s versatile design in hardware and expandable with a variety of add-on parts, and equippd with a powerful programming commands, has made the chip very popular in the industry. The pedometer controls the display by digital signals, with the sensor, which fulfills the requirement for this discussion. The process of how pedometer maneuvers is as follows, the sensor detects the vibration change in the walking, the microchip 8051 processes the data and then the lcd display the information by asked compute. This discussion will be divided by theses topics, electric component. circuitry.and programming commands process. v
