Abstract
Disclosed is a movement sensing device adapted to sense an amount of movement of an object. The movement sensing device includes a first magnetic sensor, a second magnetic sensor, a special-shaped magnetic element, and a controller. The special-shaped magnetic element has a magnetization direction, is connected with the object, and is adapted to be moved along a direction parallel to a connection line between the first magnetic sensor and the second magnetic sensor. The special-shaped magnetic element, the first magnetic sensor, and the second magnetic sensor are disposed on a plane. The magnetization direction is perpendicular to the plane. The controller is electrically connected to the first magnetic sensor and the second magnetic sensor. The controller calculates the amount of movement according to a difference between magnetic forces sensed by the first magnetic sensor and the second magnetic sensor from the special-shaped magnetic element.
