A method to research software and hardware compensation for high altitude humidity acquisition

In order to improve the acquisition accuracy of the humidity data in high altitude environmental condition, we adopt micro processing chip to control two humidity sensors with heating silk to acquire data alternately. Based on this, we advance a method that after acquiring temperatuer data by platinum resistance wire and then make software compensation and hardware compensating for humidity data, it can effectively solve the condensation phenomenon of humidity sensor caused by too low temperatur, result in reducing the humidity acquisition accuracy, even can´t work. Experimental results show that, this method can enhance the high altitude humidity acquisition accuracy effectively.
