SPEED METER HAVING PEDOMETRIC FUNCTION
First Claim
1. A speed meter having pedometric function, comprising:
- a casing, provided with a liquid crystal screen and having a power source and a circuit board that is electrically connected with the power source and the liquid crystal screen, where the circuit board is provided with a microprocessor thereon;
a gravity sensor, provided in the casing and connected with the microprocessor; and
a changeover switch, connected with the gravity sensor and the microprocessor, wherein after a user switches the changeover switch, the forward acceleration of a vehicle or the vibration produced by the human body of a user moving forward is detected by the gravity sensor, and the forward speed of the vehicle or the step count of the user moving forward is obtained via the calculation of the microprocessor and shown on the liquid crystal screen.

Abstract
A speed meter having pedometric function comprises a casing provided with a liquid crystal screen, a gravity sensor provided in electric connection in the casing, a circuit board, and a microprocessor. A changeover switch is respectively connected with the gravity sensor and the microprocessor. Thereby, the forward speed of a vehicle can be obtained by the detection of the gravity sensor and the calculation of the microprocessor when the vehicle is driven. After the changeover switch is switched into a status of walking or running, the step count of a user can be obtained by the detection of the gravity sensor and the calculation of the microprocessor and shown on the liquid crystal screen.
