The invention relates to a freezing detector based on an impedance measurement principle. The detector consists of an impedance electrode and a temperature sensor, and is used for detecting the thickness of an ice layer, converting the thickness information and temperature information of the ice layer into an electric signal, providing the electric signal to an upper computer, and enabling the upper computer to calculate a temperature signal and a freezing signal transmitted by the upper computer; whether the impedance type icing detector can be bonded to the front edge of an aircraft wing under the icing environment is determined, the surface impedance electrode of the impedance type icing detector makes direct contact with ice and can be installed at any position of the outer surface of the wing, adaptability of the icing detector to various different aircraft types is improved, and the impedance type icing detector can be applied to unmanned aerial vehicles and helicopters which are rapidly developed at present; the impedance type icing detector not only has advantages of small size and light weight, but also has invisibility which is not possessed by a common icing sensor.
