Sensor device

A sensor device, comprising:

• a housing within which a space is formed;
• a sensor module which is movably coupled to the housing and is exposed at one end thereof to an outside and configured to sense information on a state of an external member;
• and
• an electrically conducting part which is accommodated in the space of the housing and is in electrical communication with the sensor module to receive detected information transferred from the sensor module and supply power to the sensor module therethrough,
• wherein the sensor module comprises:
• a body part which is exposed to the outside;
• and
• an elastic member which is coupled to the body part and presses the body part toward the external member, and
• wherein the housing includes a band connection that provides communication between the space of the housing and an outside and to which a band member is coupled,
• wherein the band member is coupled with the external member by passing through the band connection and surrounding the external member so as to tie the housing to the external member, and
• wherein the body part is disposed such that one end thereof is in contact with the external member.
