Thamarai Selvi explained that the laser source and the resistance dependent on light (LDR)
Fixed to both ends of all tracks on the ground.
The position of the athlete should be like this, they will prevent the laser from falling on the LDR, which is the part used to measure the light intensity.
As soon as the candidate starts running, the laser from the source falls on the LDR.
Computer programs that monitor LDR readings start the timer immediately when the number of readings changes.
At the finish line, similar installations are mounted on a horizontal rod fixed at a height of 7 feet above.
Record the corresponding changes in the LDR and stop the timer.
These readings are sent to a micro-controller connected to a desktop or laptop.
After processing this data, the software will provide the final result (
Completion time for each applicant)
In PDF format.
In addition to this, if the applicant starts running before the shooting, then the laser will affect the LDR reading.
So it is inferred as the beginning of the error.
