I have a moisture-sensing dryer from the 80's that lets me select between multiple dryness levels, and it is extremely repeatable, as opposed to my parent's modern moisture-sensing dryer that that adds a fixed amount of drying time after the sensor trips, in hopes that the clothes will be dry enough. Sometimes they are and sometimes they aren't.

Ha. I modified my Whirlpool dryer with an Arduino-based automation because its own internal sensor is not precise. I used this nice sensor: https://www.adafruit.com/product/4099
