The invention relates to a method and to a device for detecting the presence of an object (6) in a lift (2) of a lift installation. According to the invention, when the lift is in operation, the colour temperature of the light hitting the colour temperature sensor is detected by a colour temperature sensor (3) arranged in the lift (2). In accordance with the comparison of a colour temperature detected when the lift is in operation with a predetected colour temperature, an object (6) present in the lift (2) is detected by a control unit (4) connected to the colour temperature sensor (3). |
