Hi
I need magnetic sensor, that produce analog voltage proportional to magnetic field.
I found linear hall effect sensors.

But I need ominipolar 1D sensor with analog output. I searched in mouser and Digikey, I could not find that type.
are there any reason for it?
basically I want to control light intensity of bulb which is proportional to the magnetic field strength regardless of North or South pole.
I know I can use bipolar type, but my idea is to control NPN transistor directly from sensor analog output. so I like if I can have omini polar sensor with 0V output at 0 Gauss.
Please help me if you know any type of these sensor?
Thanks
