Sensor module and weight exercise apparatus including the same

A weight exercise apparatus comprising:

• an exercise main body comprising a plurality of weight plates;
• a sensor module configured to detect a weight setting of the exercise main body and movement of a weight plate of the plurality of weight plates;
• a user interface unit configured to output a user interface screen;
• a memory storing at least one instruction;
• and
• a processor configured to control the user interface unit to display a user interface element indicating an exercise state of a user corresponding to the detected movement on the user interface screen, by executing the at least one instruction,
• wherein the sensor module comprises:
• a first laser sensor comprising a first measurement accuracy and a first measurement frequency to detect the weight setting of the exercise main body when the weight plate of the plurality of weight plates is in a stationary state;
• and
• a second laser sensor comprising a second measurement accuracy lower than the first measurement accuracy and a second measurement frequency higher than the first measurement frequency to detect movement of the weight plate of the plurality of weight plates when the weight plate of the plurality of weight plates is in a moving state.
