1. A dryer comprising:
a main body including a user interface;
a drum to accommodate a material to be dried;
a motor configured to provide a rotation force to the drum;
a heat pump device including a compressor, and configured to heat air to be supplied to the drum;
an electrode sensor including a pair of electrodes, and configured to output a pulse when the pair of electrodes contact the material to be dried;
a current sensor configured to output a sensed value corresponding to a magnitude of a current flowing through the motor; and
a controller configured to receive a drying course selected through the user interface, and output a control signal to control the motor and the compressor,
wherein the controller is configured to:
receive pulses from the electrode sensor and the sensed value from the current sensor, while controlling the motor to rotate the drum without driving the compressor,
determine an estimated time for the drying course selected to be completed, based on the pulses and the sensed value, and
control the user interface to display the estimated time.
