How would I go about measuring a vehicle speed sensor using a fusion brain 4?

It can't without additional circuitry.

not to hijack but I was about to ask this same question

greenman100

You need a board we have in production right now. Should be up for sale next week.

Any advanced details...like cost? And any reason you cant convert the vss pulses into a constant voltage and measure that?

greenman100

That's what this board does.

It'll probably sell for $9.99.

Ok thats very reasonable. I'll keep my eye out for it.....

I am intrested in this speed sensor, and would like to purchase my whole kit in one order. Is there any further information to the release of this item as I have not found it in the store at the moment

Cheers

What is the maximum speed these devices will be able to detect?

sxtnitehawk

much faster than you could ever wish to drive.....

most car's have a speed sensor that is a 5V square wave (or a 5v pulse), 1 pulse per revolution... to hit 650 pulses per second, you'de have to be going PRETTY fast...... seeing as for instance, my tires, have a rating of 832 revolutions per mile.......... which is 0.78 miles PER SECOND, 46.875 miles per MINUTE, and 2812.5 miles per hour

lol.........how i wish i could......but never gonna happen

take a look at your car's service manual, maybe you can find out exactly what your speed sensor does

even if lets say your speed sensor had 12 pulses per revolution, you'de still get 234mph out of this...

i'm wondering now if it's not so much that it wont handle whatever speed you could throw at it.....now i'm wondering if maybe the range is so great that it will be insensitive to slow speed or low just not quite accurate enough in a case of a speed sensor with a low pulse rate......
