Speed Checker for highways

[niteshtripathi]

Hi friends, I am building Speed checker for highway using IR sensor, 8051 and 11.0592 Mhz crystal.I have given the o/p of two sensor at two interrupts pin respectively and have run and stopped the timer. Now i have to calculate the timeperiod in second?? How to calculate??

Are you using IR distance measurement sensor? If yes, provide its datasheet.

Can you provide data sheet...

 

[betwixt]

Speed = distance/time.

You know the time by reading the timer and you know the distance between sensors because you place them yourself. All you need to do is the division calculation then multiply the result by a factor to convert to Km/h or mp/h.

i am n ot using the IR distance...i am using simple IR obstacle for interrupts

You can buy project with code from here. https://www.projectsof8051.com/speed-checker-and-overspeed-detection-for-highways/

Use 2 pairs of detectors. When first sensor pair detects the vehicle start timer and when 2nd sensor pair detects vehicle stop timer. You know the distance between the 2 pairs of sensors. Calculate speed using distance and time...


... and send auto decceleration command through SMS which will deccelerate the vehicle by reducing the gas (fuel) flow.
