hall sensor

Hi, I have this sensor --> Hall sensor to install it on my bike using an arduino nano. I was expecting it to be a NJK-5002C, but it doesn't look like it is. I'm struggling trying to figure out the pinnout, any help is welcome. It has a 3 pin automotive connector, with red, green and yellow...

Hi, this is the functional block diagram of a hall sensor IC. Can anyone please explain what is the purpose of these schmitt trigger followed by another trigger? Is single trigger cannot be able perform the function required?
