    Can Arduino sensors be used with the FB v6?

    Good morning,

    Can Arduino sensors be used with the FB v6?

    The shipping costs from the US to UK are very high so I was wondering whether I could use something like eBay number 111267142918.

    Thanks in advance,
    Dave

    if i am correct, FB uses 3.3v as input?? if that is correct, then it can read any analog input, between 0-3.3v .
    the sensor you posted seems to be working bot with 5v and with 3.3v as well. so if you just hook it to 3.3v , you should get readings from 0 to 3.3v . (meaning its ok to use it)

    i haven't ever worked with FB to be honest tho.

    Thanks for the very quick reply. I'm hoping to play with a FB v6 this week and would very much like to use it fully. I have proper OEM temp sensors, relays, parking sensor, current board and freq2volt boards - just want to have accelerometers too .

    I'm looking for some hardware tech info to if anyone can help, for connecting devices, firmware upgrades, etc.

    Thanks,
    Dave

    I'm guessing I'll need the +++ and grd the Analogue row of pins from the FB to the sensor; and the sensor x,y and z will go to the FB Ain (FB link http://store.fusioncontrolcentre.com...&product_id=50)

    Cheers

    . have in mind that accelerometers always produce a voltage output , cause of static forces like gravity, so dont be surprised if you see signal,without movement

    as for the tech info considering FB in particular, i cant help... but if you need anything else, feel free to ask!!

    I'm aware of statics forces and planned to use the - ignore if the value is..... but thanks for the reminder. From that I would expect to see all three about the same with 3.3v and grd applied .

    Any ideas what the other connectors on the accelerometer are?

    Thanks again

    Cheers

    yiap.

    GS : the pin which allow's you to select sensitivity (1,5 or 6g). i think low input to that pin, is 1.5g , high is 6g.
    ST: is selft test. ignore it
    SL: sleep mode. in my accelometer, if this pin is not HIGH, it does not work... just sort it with VCC.
    OG: this pin is high, when all 3axis are sensing 0g.

    but dont take my word for it, becouse i can be making a mistake... ALL the information you need, can be found here:
    https://www.sparkfun.com/datasheets/...l/MMA7361L.pdf the datasheet for the chip, this sensor uses... (you anyway need it, to convert voltage to actual "g" )

    Cheers Settra, your help has made things much clearer - thanks bud .

    I think I'm looking trying that sensor and having the 3.3v (with GS and SL shorted to 3.3v) from the Fusion Brain, ground from the Fusion Brain, and x/y/z sensor outputs to Fusion Brain.

    RRFusion research time next .

    Thanks so much .

    Yes the inputs are 3.3v.

    And you won't get 3 equal signals on a 3-axis accelerometer when sitting there. You will get 1G in the Z direction and then hopefully 0G in the X and Y just from being idle.
