Sensing device 11 that can be easily attached or detached by passing an object through the gap generated in the state and then bringing the first curved portion 742b and the second curved portion 743b into contact again to insert the object into the second insertion hole 741 ) can be attached to objects.

For example, in a state in which the other ends of the first curved portion 742b and the second curved portion 743b are spaced apart from each other by a predetermined distance, a bag strap is passed through the gap, and then the first curved portion 742b and the second curved portion 742b are separated. A backpack strap may be inserted into the second insertion hole 741 by bringing the portion 743b into contact again.

In addition, a thin object such as clothes and a tablet PC is placed in the gap generated when the other ends of the first curved portion 742b and the second curved portion 743b are separated by a predetermined distance, and then the first curved portion ( 742b) and the other end of the second curved portion 743b come into contact again so that the second magnetic member 750 and the third magnetic member 760 are coupled through magnetic force, so that the housing 100 can be mounted on a thin object. there is.
