As shown in Figure 2, be the schematic diagram of automatic dehumidifying control circuit embodiment illustrated in fig. 1.Humidity detection unit 110 comprises the hygristor MS and the first resistance R1, the second resistance R2 being connected to the series connection of working power two ends and the 3rd resistance R3, voltage comparator U1 that are connected to the series connection of working power VCC two ends; The positive input (1 pin) of described voltage comparator U1 is connected to the common port of hygristor MS and the first resistance R1, for detecting the first resistance R1 both end voltage, reverse input end (2 pin) is connected to the common port of the second resistance R2 and the 3rd resistance R3, for detecting the second resistance R2 both end voltage.As shown in Figure 2, the control signal that humidity detection unit 110 exports is that voltage comparator U1 exports low and high level signal.Be appreciated that in other embodiments, humidity detection unit 110 can also adopt other Humidity Detection modes and export dissimilar control signal, and is not limited to the mode that the present embodiment provides.
Switch control unit 120 comprises relay K, the diode D1 of the 4th resistance R4, the 5th resistance R5, metal-oxide-semiconductor Q1, the work of control dehumidifier; Described humidity detection unit 110 exports one end of described control signal and comparer U1 output terminal (3 pin) is connected with the grid of metal-oxide-semiconductor by the 5th resistance R5, and source ground, the drain electrode of described metal-oxide-semiconductor Q1 are connected with relay coil part K.Diode D1 is connected in parallel on relay K two ends, and the positive pole of diode D1 is connected with the drain electrode of metal-oxide-semiconductor, negative pole is connected with working power VCC positive pole.The positive pole of described LED light is connected with one end that humidity detection unit 100 exports control signal by the 4th resistance R4, and the negative pole of LED light is connected with working power VCC positive pole.

The principle of work of circuit is described with the circuit diagram shown in Fig. 2 below.
When air humidity is little, hygristor MS resistance is very large, and when air humidity is larger, the resistance value of hygristor MS can decline a lot, and along with the difference of humidity, the resistance of hygristor MS presents corresponding change substantially.The change of control voltage is carried out by the resistance controlling hygristor MS.Hygristor MS and variable resistor R1 forms the maximum that humidity reaches jointly.Second resistance R2 and the 3rd resistance R3 is used for providing reference voltage value.VCC passes through C1 filtering, for rear class components and parts are powered.
It is specific as follows: when air humidity is in normal range, hygristor MS resistance is larger, the reference voltage that first resistance R1 both end voltage provides than the second resistance R2 and the 3rd resistance R3 is low, now the positive input 1 pin voltage of voltage comparator U1 is less than reverse input end 2 pin voltage, U1 output pin 3 output low level, now metal-oxide-semiconductor Q1 disconnects, and relay K 1 dead electricity does not work, dehumidifier does not work, and LED light does not work.
After air humidity reaches the standard temperature threshold value of setting, MS resistance reduces, make the first resistance R1 both end voltage higher than reference voltage, and voltage comparator forward input pin 1 pin voltage is higher than reverse input pin 2 pin, now 3 pin of U1 export high level, high level lights LED by the 4th resistance R4, and it is very high that LED lights display air humidity.High level provides high level by the 5th resistance R5 for Q1 grid simultaneously, and make Q1 conducting, Q1 conducting makes relay coil part K obtain electric work, and switch sections K-1 adhesive, dehumidifier work, LED light is bright.
