Result
When a magnet's South pole is facing the sensor detection area, the indicator light on the sensor illuminates, and the analog output value is greater than 512. When a magnet's North pole is facing the sensor detection area, the indicator light on the sensor illuminates, and the analog output value is less than 512. (When no magnetic pole is detected, the analog value is between 500-520.)
