When the ambient humidity changes, the capacitance of the capacitive humidity sensor 111 changes, i.e., when the relative humidity increases, the humidity-sensitive capacitance increases, and vice versa (capacitance typically between 48 and 56 pf). The conversion circuit of the capacitive humidity sensor 111 converts the capacitance change amount into a voltage amount change, and the output of the sensor changes linearly in a range of 0 to 1v in response to a change in relative humidity of 0 to 100% rh. And finally calculating the volume water content at the control terminal according to the parameter change value.
