Disclosed is an ultrasonic sensor assembly with a sensor cell which is insensitive to a change of temperature. The system includes: a sensor cell which transmits an ultrasonic signal for detecting an object and receives a reflection signal which is a signal reflected by the object; a heating line which is attached to the outside of the sensor cell to receive battery power from a vehicle battery, and generates heat; and a vehicle control module which controls the supply of the battery power by the heating line based on a result of monitoring the external air temperature of the vehicle. |
