3.3 No Analog output (remains at 0V).

Check wire connections and ensure that you are powering the sensor.

Likely reasons:

 Power, Ground or output connection in the wrong place.

 power supply is off or faulty.

3.4 Analog output stays at 0.5V.

Likely reason:

 Possible sensor fault.

o Check sensor orientation (see Figure 3).

o If in error analog output will stay at 0.49 - 0.5 V.

o Digital output will remain on the baseline (0 counts).
