DIGITIZED TUNING RANGE CHECKING DEVICE FOR ELECTRIC HORN WITH AUTOMATIC RECORDING

This project is concerned about checking the Tuning Range of an Electric Horn used in automotives and to display the values in digitized format. The displayed values are interfaced with computer for future advancement. The vibration of the electric horn is used for measuring the tuning range, which decides its life expectancy. The existing system used for measurement is an analog device, which requires frequent calibration and appended labor for documentation. The project involves measuring of tuning range with the help of the Accelerometer. The output from sensor is transmitted to microcontroller, which is interfaced with LCD and UART for display and future enhancement. If the displayed value is in-between tuning range, the work piece can be allowed for dispatch. The appropriate horns are separated using gear motor mechanism. Thus, the proposed system supports the workers at Electric Horn manufacturing industries to increase the productivity. It eliminates the vision problem experienced by workers while measuring analog values.
