Device for automatically controlling humidity

[0017] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0018] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0019] Such as figure 1 , 2 As shown, the present invention provides a device for automatically controlling humidity, including a humidity sensor unit 1, a controller unit 2, an external network signal receiving unit 3, an information sending unit 4, and an actuator unit 5. The output of the humidity sensor unit 1 The terminal is electrically connected to the signal input terminal of the controller unit 2, and the control output terminal of the controller unit 2 is electrically connected to the information sending unit 4 and the actuator unit 5, respectively. The controller unit 2 also It is in communication connection with the external network signal receiving unit 3.

[0020] The humidity sensor unit 1 includes a humidity sensitive resistor RB, a first resistor R1, a first capacitor C1 and an operational amplifier 11. The first resistor R1, the first capacitor C1 and the humidity sensitive resistor RB are connected in series in sequence Between the AC power supply and the ground, the inverting input terminal of the operational amplifier 11 is electrically connected to the input terminal of the humidity sensitive resistor RB, the non-inverting input terminal of the operational amplifier 11 is provided with a humidity threshold, and the operational amplifier 11 The output terminal of is electrically connected to the signal input terminal of the controller unit 2.

[0021] The controller unit 2 is a single-chip microcomputer.

[0022] The external network signal receiving unit 3 is a SIM card signal connection circuit.

[0023] The external network signal receiving unit 3 is a WIFI signal receiving circuit.

[0024] The working process of this example: the humidity sensor unit 1 monitors the voltage level of humidity in real time, and compares the voltage level with the humidity threshold set by the operational amplifier 11. If the real-time voltage level is higher than the humidity threshold , The output terminal of the operational amplifier 11 will output a high-voltage signal to the controller unit 2, and the control output terminal of the controller unit 2 controls the actuator unit 5 to take corresponding actions to reduce humidity, and also controls the information sending unit 4 to receive signals through the external network Unit 3 sends a prompt message to the user; if the real-time voltage level is lower than the humidity threshold, the output terminal of the operational amplifier 11 will output a low-voltage signal to the controller unit 2, and the control terminal of the controller unit 2 will not start

[0025] The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the present invention. Within the scope of protection.
