The present invention relates to an electronic apparatus which can be worn on a body of a user. The electronic apparatus comprises first and second wearing units which can be coupled to each other and separated from each other. In this case, the first wearing unit comprises : a first sensor unit which may detect movement of the first wearing unit and which may generate first movement information; a first coupling part which may be coupled to the second wearing unit; and a first communication unit which may communicate with an external device and the second wearing unit. The second wearing unit comprises : a second coupling part which may be coupled to the first coupling part; a second sensor unit which may detect movement of the second wearing unit and which may generate second movement information; and a second communication unit which may communicate with the first wearing unit. The first wearing unit further comprises a first control unit configured to control the first communication unit to receive the second movement information from the second wearing unit and to transmit at least one of the first movement information and the second movement information to the external device when it is determined that the first coupling part is coupled to the second coupling part. The second wearing unit further comprises a second control unit configured to control the second communication unit to transmit the second movement information to the first wearing unit when it is determined that the second coupling part is coupled to the first coupling part. Accordingly, more accurate medical health information analyzed based on the movement information can be provided.(101) First control unit(200) First sensor unit(203) First coupling part(205) First communication unit(AA) First wearing unit moduleCOPYRIGHT KIPO 2017
