Fusion USB I/O Board - What type of sensors would you like to see?

[greenman100]

The cost thing makes sense and so does the concern of off-axis mounting. But measuring the vertical change at one point of the car won't tell you anything about yaw, pitch or roll. You'd need 2 vertical accelerometers at two known positions to provide any useful info there. But as long as it's in the box for the same price, sweet

People that turn their own suspension are interested in vertical G-force.

how many g's can this sensor read up to? how many g's will damage it? if there rated pretty high then these can be awsome suspension sensors on the outboard suspension, by the wheels. the ocillations & vibrations there are pretty high though I think

can read up to +/- 6G, rated to withstand +/- 2000G

that'll work fine then, last thing, do you think they'd be affected by a close by magnetic field? these would make a great tool for mechanics in diagnosing suspension issues, they could be temporarily attached with heavy magnets...

I would not expect magnetic fields to be a problem, though I have not tested it.

I would contend that a linear potentiometer parallel to the coilover (or spring if they're separate) is much more useful. G's on the unsprung weight of the car are solely a function of the shape of the road and the sidewall deflection of the tire. Anyway, it's not a bad thing to have them. 6 G's is plenty of range for the accel's if they're mounted on the body.

You are correct. Some people expressed interest, though, and 2-axis is nearly the same price as 3-axis.

Hi im fairly new to this forum, joined a while ago but havnt posted much yet!

can i just say this bit of kit looks amazing! my brain is going crazy thinking of the endless possibilities!!

it would be good to see:

oil temp
water temp
air flow
fuel flow
tyre temps
brake temps
speed
rpm ( with a shift light!)
police radar detector - for um detecting traffic accident areas!

oh and how could tyre pressure be done?

i presume this isnt for obd2 only?

the main reason i ever started looking at car pc's was to have all the obd2 info on screen but then found out my car was pre obd2 so this would finish my install off perfectly! just what ive been looking for!!

oil and water temp can be done with our temp sensors
air and fuel flow are too specialized, the demand is too low
tire temps, I have no idea, maybe an IR sensor
same on brake temps, either use our sensors or an IR sensor

this doesn't use OBD at all, it's self contained.

hmm, maybe hack one of those touchless 'laser' thermometers? I'll look in to it =]
