Hello. I have Frsky Hall gimbals. Each hall sensor has 3 cables (probably VCC, GND, Data). Is ti possible use this senzor with Arduino for measuring RPM? What data hall sensors sends? Is it analogue, PPM, PWM or something else?
Thanks.
DC 3.0 ~ ± 0.5V
make photo from sensor. which one is it? any marking on it?
I suspect that @jasin755 may be referring to 2 axis control sticks used in RC transmitters in place of 2 axis sticks using potentiometers
I replaced the pots in my RX transmitter with "Hall effect" sticks some tears ago and no other changes were required, so I suspect that the sticks have circuitry in them to output a voltage to replicate the output from pots
However, this is speculation until @jasin755 confirms exactly which device he is referring to
Is it part of an RC transmitter or some other Frsky device ?
Yes I mean this sticks. You can replace it.
so, if this is replace for Potentiometer module, this mean it is an analog connection and hall sensor itself.
I am not sure how the Hall sensor works in relation to the sticks, but as the Hall effect sticks were a direct replacement for the pot based sticks in my Taranis you could presumably read them with analogRead(). However, I don't know what voltage they work at when in the transmitter
DC 3.0 ~ ± 0.5V
Where did you measure that ?
in google
I doubt that you measured it in Google but please post a link to where you found the information
Are you aiming to use the stick assemblies whilst they are also being used by the transmitter or as stand alone sticks ?
Why not establish the polarity of the connections to the sticks and try reading the output using analogRead() ?
