    摘要： A laundry appliance having: a treatment chamber; and a humidity measuring arrangement for measuring the humidity of at least one item to be treated. The humidity measuring arrangement has a sensing capacitor and a capacitance sensing unit for measuring a capacitance of the sensing capacitor and obtaining an indication of the humidity of the item to be treated according to the measured capacitance. The sensing capacitor has first and second electrical conductors and a dielectric. A volume of the chamber forms part of the dielectric. The appliance has an extension member configured to be positioned within the chamber for extending the first electrical conductor within the laundry treatment chamber. The extension member has an extension conductor and a coupling conductor, and the extension conductor can be electrically coupled to the first electrical conductor through a capacitive coupling via the coupling electrical conductor.
