Sensor ball and home appliance system having same

A sensor ball comprising:

• a case having at least one curved surface;
• a first board disposed within the case and on which a processor is disposed;
• and
• a second board electrically connected to the first board and on which a plurality of sensors are disposed,
• wherein a first group of the plurality of sensors are disposed on an outer surface of the case or an end of the second board, and a second group of the plurality of sensors protrude from the outer surface of the case or the end of the second board, and
• wherein in a state where the processor is paired with a washing machine, the processor is configured to determine laundry tangles based on sensor data sensed by an acceleration sensor and a gyro sensor, and transmit determined laundry tangle information to the washing machine.

• wherein a first group of the plurality of sensors is disposed on an outer surface of the case or an end of the second board, and a second group of the plurality of sensors protrude from the outer surface of the case or the end of the second board,
• wherein the sensor ball further comprises a third board attached in place of the second board and electrically connected to the first board and in which a plurality of sensors are disposed, when the second board is detached from a groove in the case,
• wherein the first board further includes a communication module configured to perform paring and wireless communication with a home appliance, and
• wherein the communication module is further configured to:
• when the paired home appliance is a clothing manager, transmit sensor data sensed from a spectrometric sensor, an acceleration sensor, a gyro sensor, a humidity sensor, and a dust sensor to the clothing manager,
• when the paired home appliance is an air purifier, transmit sensor data sensed from a gas sensor and the dust sensor to the air purifier, and
• when the paired home appliance is a refrigerator, the sensor data sensed from the gas sensor and the humidity sensor to the refrigerator.
