A driver circuit used for driving the alarm device comprises a transistor TR6 and a resistor R6. The base of the transistor TR6 is connected to the processor via a resistor R6. The emitter is grounded. The collector is connected to one end of the buzzer 23 (alarm device) . The other end of the buzzer is connected to the power supply.
The control system of the present invention also comprises a stepper motor driver to drive a stepper motor， which is connected to the processor through the optical isolator. When the user needs to humidify the air， he can press AN6 or use remote control terminal to send the instruction of opening the tank lid. When the processor checks the signal of pressing AN6 or the instruction of opening the tank lid， the optocoupler provides a pulse signal to the stepper motor driver. The motor runs forward， and drives the retractable door to move to the right. Then the Hall switches mounted on the two edges of the tank are off. When the tank lid is opened completely， magnetic steel of the retractable door aims at the Hall switch KR on the right side. Then the Hall switch on the right is turned on. When the processor receives the signal， it does not provide signal to the optocoupler， and makes the stepper motor to stop working. When the user does not need to humidify the air， the user presses AN6 or sends an instruction of no humidification via a remote control terminal， the processor receives the signal of AN6 or the instruction of no humidification. Then it provides the stepping motor with a pulse signal. The motor runs backward， and drives the retractable door to move to the left. At that time， the Hall switches mounted on the two edges of the tank are off. The retractable door continues moving to the left. When it reaches to the leftmost position， the magnetic steel of the retractable door aims at the Hall switch KL on the left edge of the tank. The Hall switch KL is turned on. The processor receives this signal， and stops the stepping motor. The tank will be covered with the lid.
Figure 3 illustrates a temperature or humidity detection and processing circuit diagram according to present invention. As shown in Figure 3， the temperature and humidity detection and processing circuits can be implemented using the same circuit diagram， which mainly includes the temperature or humidity detector constructed of an operational amplifier OP3 and the external resistor R13， R12， R11， Hygristor or thermistor Rt， R10， temperature or humidity upper limit comparator which is constructed of the operational amplifier OP1 and its peripheral resistors R7 and RW1， temperature or Humidity lower limit comparator which is constructed of the operational amplifier OP2 and the external resistors R9， RW2， and two optocouplers. The non-inverting input of the first threshold eomparator OP 1 inputs the first threshold voltage which is divided by RW1 through the power Ec. The inverting input of the first threshold comparator OP1 is connected to the output of the temperature or humidity  sensor. The output of the OP1 is connected to processer via the first optocoupler PE1. The non-inverting input of the second threshold comparator OP2 inputs the second threshold voltage which is divided by RW2 through the power Ec. The inverting input of the first threshold comparator OP2 is connected to the output of the temperature or humidity sensor. The output of the OP2 is connected to processer via the first optocoupler PE2.
The first threshold comparator OP1 compares the output signal of OP3 with the first threshold value. When the output signal of OP3 is greater than the first threshold， the comparator OP1 outputs a low level signal. The light-emitting diode in the first optocoupler PE 1 conducts. The photoelectric tube in optocoupler PE 1 conducts. The first input port of the processor obtains a low-level signal. Then it sends signals to the alarm device and the display. The alarm device gives an alarm. The display shows the words that the temperature or humidity is higher than the upper limit. When the temperature is higher than the upper limit， the processor outputs a high level signal to the base of TR3 to start the cooler. When the humidity is higher than the upper limit， the processor provides signals to the photoelectric isolator to reverse the stepper motor. The lid of tank is closed. When the output of OP3 is lower than the first threshold， the comparator OP1 outputs a high level signal. The light emitting diode and photoelectric tube of the first optocoupler PE1 pick off. The first input of the processor obtains a high-level signal. The second threshold comparator OP2 compares the output signal of OP3 with the second threshold value. When the output signal of OP3 is lower than the second threshold， the comparator OP2 outputs a low level signal. The light-emitting diode in the second optocoupler PE2 conducts. The photoelectric tube in optocoupler PE2 conducts. The second input port of the processor obtains a low-level signal. Then it sends signals to the alarm device and the display. The alarm device gives an alarm. The display shows the words that the temperature or the humidity value is under the lower limit. When the temperature is under the lower limit， the processor outputs a high level signal to the base of TR2 to start the heater. When the humidity is under the lower limit， the processor provides signals to the photoelectric isolator to make the stepper motor to run forward. So that the lid of tank is open. When the output of OP3 is higher than the second threshold， the comparator OP2 outputs a high level signal. The light emitting diode in the second optocoupler PE2 and the photoelectric tube in the optocoupler PE1 pick off. The second input of the processor  obtains a high-level signal.
