This invention is applicable to new and old clothes dryers, even clothes dryers that have a moisture sensor built-in because this invention measures the humidity. The invention, Retrofit Moisture and Humidity Sensor and Automatic Shutoff device for Clothes Dryers, relates to an apparatus and methods for reducing energy consumption for gas and electric domestic or industrial clothes dryers by placing or retrofitting a moisture/humidity sensing apparatus inside or unto the drum of a clothes dryer. The Sensor is able to remotely/wirelessly communicate to a Receiver device. The clothes dryer is directly plugged into the Receiver. The Receiver device serves the purpose of shutting the power to the clothes dryer when the items in the clothes dryer are dry as indicated by the Sensor. The moisture/humidity detecting sensor has various levels of dryness to choose from. Although moisture detecting dryers are readily available, these types of dryers are not in the price range of most consumers. The advantage of this inexpensive power saving concept is that it does not require any mechanical alterations to the clothes dryer (unless being installed on a gas operated clothes dryer). It can be installed on older clothes dryers or newer dryers. Second, the Sensor can detect the humidity which is a far more accurate way of determining when the items are dry. In brief, the small moisture/humidity detecting sensor apparatus is placed inside the drum of the clothes dryer. The clothes dryer is directly plugged into a Receiver which is plugged into the 120V or 240V electrical outlet. When the Moisture/Humidity Sensor apparatus detects that the items are dry it wirelessly communicates to the Receiver which cuts the power to the clothes dryer. The Receiver can be overridden from on/off. |
