ss49E or AH3503 hall sensor

Using Arduino General Electronics
1

Hi, im thinking in making a clutch paddle, first idea was using a potentiometer, like most xbox/ps5 controllers. But then i read about the hall sensors, i looks great... i will go with them.

I have searched in google and found those two models, AH3503 seems to be more accurate... but is it worth it? A clutch shouldnt need a lot of accuracy, but maybe the ss49e has a very low accuracy...

What do you think?

thanks

What do you mean by accuracy. There is nothing in the data sheets that specifies accuracy and as you say does it really matter. Do you actually need to know the absolute magnetic field strength?

I found this (PDF) AH3503 Datasheet - LINEAR HALL-EFFECT SENSOR

it says at the begining ". Extremely Sensitive" maybe accuracy its not the correct word.

I will use the value sent by the sensor to move a progress bar in a joystick (something like a throttle, that will push more or less based on that measure)

My question is if ss49e its "rubbish" "poor" "normal" or "better" compared to AH3503. in terms of sensibility, I mean, a little movement of the magnetic element should make a change in the readings.

thanks.

You are asking for a subjective answer. You need to define the terms better. That old alarm clock in the corner that has not run for years is 100% accurate two times a day. Also it helps if there is a data sheet for each item and what the test parameters are.

The 3503 has a sensitivity of about 13.5mV/mT
The 49e has a sensitivity of about 18mV/mT
So the 49e is a little more sensitive.
The linear range for the 3503 is about +/- 90
The linear range for the 49e is about +/- 100
The 49e is more linear
The response time of the49e is 3usec.
The 3505 does not specify the response time but gives a frequency response of 23kHz, which implies it's slower than the 49e.

I would buy the SS49e

thanks! Thats what I need, someone who could tell me which parameters to compare and which is better.

Thank you.

Have fun!
Let us know how it works out.
