| Abstract: | Intelligent odometer is designed using hall effect to avoid the defect of mechanical odometer. The speed and mileage are measured by the hall sensor by method of pulse detection. The double frequency circuit used can improve the precision of the system. User interface of the sysem is designed. It can automatic alarm if the speed exceeds the limit. The max speed can be setup by the user. The speed can be measured as well as controled in the system. |
