There is 6 pin in but just 4 pin out. I just tought that 3 of the sensor pin are connected together at pin output H1 but the internal connection like as below
H one to GND
H other to H1
A one to A1
A second not connected
B one to B1
B second not connected
But other A should be at 5V
and other B should be at GND with 10K by the wiring refer.

could some one tell me the solution? The sensor should be hot for having efficient data. and the best wiring connection was given at above.
The connection on below should be pulled down at B to GND?
