how to USE hall effect sensor ?

[expelleior]

hi,
I want to use hall effect on bike wheel but not sure how to use it. Is a 10k resistor between 5+ and output all that is needed ? (pins 1 and 3)

will it toggle to ground/zero while connected to 5+ ?

this blurb was on the site which has the sensor:

Bit of an application note for the unwary

Looking from the front where the writing is
Pins run from left to right 1,2,3

Pin 1 is +5v (or +3.3v)
Pin 2 is Gnd
Pin 3 is Output

Put a 10K resistor between pins 1 & 3. The output will then toggle between High and Low with the magnet. Upi can feed that directly onto a digital pin of a PicAxe or Arduino }}

Hi,
Whatever hall effect sensor you have, its a 3 pin sensor with comparator, amplifier+Filter/schmitt trigger and voltage regulator integrated in it. Thus there are three pins one for VDD +5V input to regulator, second is gnd and third the output pin. The output pin gives directly digital logic output. Which you can give to any digital circuit.
Just refer the dia below:
