Abstract

A content detection device is provided. The content detection device includes a first sensor and a controller. The first sensor is disposed near a space. The controller is coupled to the first sensor and detects a state of the first sensor. The controller performs a determination operation to determine whether an object is disposed in the space according to the detected state of the first sensor.
