The control module inputs are digital. A voltage greater than 2 V is regarded as "OFF" and lower than 2 V as "ON". The control module calculates the
position of the window by counting the number of changes between "ON" and "OFF". The control module will count 2 changes per revolution of the
motor from each Hall sensor. Since the sensors are displaced by 90 degrees, the control module will detect a total of 4 changes, displaced by 90 degrees,
each revolution.
