Abstract
A sensor device is configured to be disposed on a surface of a side of an object. The sensor device includes a casing, and the casing has a first side that is distant from the object and a second side that is relatively closer to the object. A first induction coil set is disposed on the first side, and a second induction coil set is disposed on the second side. The sensor device further includes a control circuit board. The control circuit board includes a connection line that is electrically connected with the first induction coil set and the second induction coil set, and a microcontroller. When the sensor device is in operation, the microcontroller determines a position change of a metal item on another side of the object according to a physical quantity difference between the first induction coil set and the second induction coil set.
