Operation principle of the present utility model is: refer to Fig. 1, flat roof type alternating voltage is become through T step-down, R1 and R2 current limliting and VS1 and VS2 voltage stabilizing, slicing, this alternating voltage becomes DC voltage through RP1 adjustment sampling, RS step-down and Q rectification, again by after C3, R3 and C4 filtering current limliting, add on ammeter A, the resistance of RS changes along with the change of humidity, and the resistance of the higher RS of ambient humidity is less, and the DC current flowing through ammeter A is larger.
When humidity is lower, the electric current flowing through R4 is also less, and voltage comparator U1 exports high level because of the voltage of inverting input lower than the reference voltage of in-phase input end, makes VT conducting, relay K adhesive, external humidifier energising work, along with the continuous rising of air humidity, when humidity reaches setting humidity, voltage comparator U1 because of reverse input end voltage higher than its in-phase input end voltage output low level, VT ends, and K discharges, and external humidifier working power is cut off.So repeatedly work, ambient humidity can be made to control the humidity range set.
