Relais open close by gps

Hello, I would like to know if it is possible to operate a relay depending on the speed of a vehicle. ex open above 30 kmh and close below 30 kmh? THANKS

I think so, because the Waze App informs you when you exceed highway speeds.
So the calculation is possible. But I never tried to do it.

You could certainly use an Arduino to read the speed from a GPS and decide what to do depending on the speed reported.

Yes. You will need to design some hardware and software to accomplish this.

hello I found this sketch that works very well with an LED but I don't know how to integrate a relay
