A method and a device for detecting the presence of an object in an elevator car of an elevator system that has a control unit include a color temperature sensor. The color temperature sensor is integrated into the elevator car to acquire the color temperature of the light incident on the color temperature sensor during elevator operation, and an object present in the elevator car is detected by the control unit connected with the color temperature sensor by comparing the color temperature acquired during elevator operation with a previously acquired reference color temperature.
