Abstract
The working principle of sensor based on hot wire is described. To take a crosswind sensor for example, the structural design,experimental model and data analysis of a hot wire sensor,and a method that can eliminate the influence of ambient temperature are put forward. The mathematical model and design method of hot wire sensors at constant voltage or constant temperature are expounded emphatically. A hot wire crosswind sensor is constructed and the performance of this sensor operated at constant voltage or constant temperature is experimentally investigated.
