# Hall effect sensor operational distance from magnet

I want to use a this hall effect sensor to detect the presence of magnet. I'm pretty sure I understand how to use the hall effect sensor, but I'm not sure how to calculate the distance the sensor can detect a magnet of a given Gauss. I'm not even sure that the Gauss rating is relevant to the question.

The Output On rating is listed as 35G and the Output Off is listed as 25G. If I use a magnet like this one (13,200 Gauss), can it be detected up to 6 inches (15 cm) away?

I found an online calculator to use but it appears to calculate the rating between two magnets and not a magnet and a sensor.
