In order to improve the conditions of high altitude and humidity data acquisition accuracy, and avoid the phenomenon of humidity sensor condensation due to lower temperature, the authors adopt DSP to control two humidity sensors with heating silk to acquire data alternately. Based on this, they advance a method that after acquiring temperature data and then make hardware compensating for humidity data; it can effectively avoid the phenomenon of humidity sensor condensation due to lower temperature, Field experimental results show that, the method can solve the humidity senser condensation because of the low temperature, and improve the accuracy of humidity data acquisition.
