What is Sensor Dry feature in a Samsung Dryer?

Please note:
• During a Sensor Dry cycle, you may notice the drying time has changed, which is normal
• Samsung recommends to dry the same items at each load. If you are drying a mixed load, such as jeans and shirts, the cycle may end before the heavy items or jeans are dry. This is due to centrifugal force. The heavier items will tend to stay at the rear of the drum, away from the humidity sensor bars, and the lighter items will tend to stay in the front of the drum
