The invention belongs to the technical field of ice prevention and removal, and relates to an icing condition detection method based on detection of environment liquid water content. The icing condition detection method based on detection of the liquid water content in the environment relates to an icing condition sensor, the icing condition sensor comprises a probe assembly and an electronic device assembly which are located in airflow, the probe assembly comprises two platinum resistance probes and a shell heater, and the electronic device assembly comprises three circuit boards. Platinum resistance thermometers are installed in two airflow channels of the detector, and a shell heater is arranged on the surface of the whole detector. The two platinum resistors are arranged in humid air flow and dry air flow respectively, the two same platinum resistors are heated to 50-100 DEG C by applying the same excitation voltage to the two same platinum resistors, the humid air flow contains liquid water, the liquid water impacts on the humid platinum resistor, the temperature is lowered, and the resistance value is lowered. A voltage signal is obtained by sampling and comparing the resistance value difference of the wet platinum resistor and the dry platinum resistor, and the content of liquid water in the air is obtained through calculation.
