Claim:
1. A dryer monitor comprising: a temperature sensor that senses temperature information associated with a dryer cycle of a clothes dryer; a humidity sensor that senses humidity information associated with the dryer cycle; and a controller that calculates an absolute humidity (AH(P)) based on the temperature information and the humidity information, calculates a reference point angle based on the absolute humidity and the temperature information, the reference point angle defined as an angle made by a line from an origin to a point defined by the absolute humidity and the temperature information in an AH(P) versus temperature coordinate space, determines that textiles in the clothes dryer are dry if at least the reference point angle is less than a reference value, and in response to determining that the textiles are dry, at least one of generating a dryness indicator on a user interface of the clothes dryer and turning off the clothes dryer.
