Sensory reheat is a frequent task button on a microwave that measures the amount of steam emitted from food. The internal sensors detect how long and at what power the item needs to be cooked. It takes a few moments during cook time for the sensors to detect the amount of steam inside of the microwave. The time adjusts automatically to a countdown and stops when the food is warmed. Sensory reheat works with any food item, but if your leftovers are particularly dry, the sensors can detect steam with more precision if you add a little bit of water to whatever you're reheating.
