Abstract: A sensor for sensing a fill level of a space includes a housing, a circuit board, a camera, a distance measuring sensor and a controller. The controller is in communication connection with the camera and the distance measuring sensor to calculate the fill level of a space according to the input from the camera and the distance measuring sensor. An elevator includes the sensor for sensing the fill level of the elevator car space. A method for sensing and determining a fill level of a space like an elevator car without utilizing the gravity load can better identify the objects in the space and further calculate the fill level of the space according to the identified images, and can be used as a substitute or a beneficial supplement for gravity load determination.
