By adjusting a variable resistor to be changes in the voltage to simulate a humidity sensor, Led display shows the current value of collected humidity. Another set of four buttons, keys can be adjusted through the system parameter setting. When the humidity is higher than the value of humidity humidity ceiling or below the limit, alarm lantern light. When the humidity is less than the target and not the proportion of humidity adjustment range, the system output high, humidity humidifier will work at full capacity, when the humidity reached the proportion of adjustment range, the system output PWM pulse, humidity will be intermittent humidifier work to ensure that humidity and gradually achieve the target value. The eventual realization of a closed-loop intelligent humidity control instrument
