An ice detector probe senses an ice deposition from an air mass flowing relative to the probe. The probe includes a support for installation of the probe to receive the airflow and an element formed on a substrate having a sensing surface which directly receives the airflow. The element heats the sensing surface to melt an ice deposition formed thereon. The resistance element also senses the sensing surface temperature during heating and provides an output representative of such temperature.
