Abstract

See full text

A dryer monitor detects when textiles in a dryer are dry, detects when textiles in a dryer are overdry, and/or may count dryer cycles. The dryer monitor includes a humidity sensor, a temperature sensor, a controller and various status indicators. The humidity and temperature sensors may be located outside the drying compartment of the dryer. In the case of a clothes dryer, the humidity and temperature sensors may be located outside the drum of the dryer and may be located, for example, in the exhaust compartment of the dryer. The dryer monitor determines dryness of items in the dryer, and may also determine whether the items are overdry, based on humidity information received from the humidity sensor. The dryer monitor counts dryer cycles based on temperature information received from the temperature sensor.
