I am working on the Arduino magnetic levitation project and it requires "ratiometric" hall effect sensors. On amazon and adafruit there are no hall effect sensors that are explicitly "ratiometric". Based on a quick google search I know that being ratiometric means its output changes based on a change input or supply voltage, but this makes it seem like all Hall Effect Sensors are ratiometric. Can I buy whatever is on amazon or do I need to go elsewhere and buy a ratiometric hall effect sensor?
Thank you, the help is greatly appreciated!
