[0022] The automatic dimming smart curtain of the present application uses the Ardu i no Uno board as the main controller, uses the photoresistor acquisition module to sense the external light intensity, and performs the corresponding action after processing and comparing it with the set value in the storage. The steering gear performs forward and reverse rotation to control the change of the angle of the blinds and the contraction up and down. It can automatically adjust with the external light intensity without manual control. In addition, the infrared remote control module can be used to control the opening and closing of the smart curtains with a remote control.

[0023] For example, in the automatic dimming smart curtain provided in one embodiment, Figure 2 As shown, the servo assembly 200 includes a first servo 210 for controlling the upward and downward contraction of the shutter assembly 100 and a second servo group 220 respectively connected to each of the shutters 110, the second servo group 220 includes a plurality of second servos 221, both ends of each of the shutters 110 are connected to the output shaft of the second servo 221, and the rotation of the second servo 221 drives the rotation of the shutter 110.

[0024] For example, in the automatic dimming smart curtain provided in one embodiment, Figure 2-3 As shown, the shutter assembly 100 includes two oppositely arranged frames 120 and a plurality of vertically distributed shutters 110 connected between the two frames 120, the frame 120 includes a frame body 121 and a cover plate 122, a slot body 123 for accommodating the second servo group 220 is provided in the frame body 121, and an opening 124 corresponding to the slot body 123 is provided on the cover plate 122.

[0025] During assembly, the second steering gear group 220 is first installed in the slot 123 and then the cover plate 122 is closed, so that the steering gear can be assembled more easily.

Both ends of each louver 110 are connected to the second servo 221, and the synchronous movement of the second servo 221 at both ends can keep the fan blades horizontally contracted.

[0028] For example, in the automatic dimming smart curtain provided in one embodiment, Figure 2-3 As shown, a fixing frame 126 for fixing the first steering gear 210 is provided on the top of the frame body 121 .

After the set number of circles, the curtain will automatically stop, avoiding the trouble of manual operation.

[0031] This application uses an infrared remote control to transmit signals, an infrared receiving module to receive signals, and the R3 UNO board as the main program execution hardware, so it is necessary to assign values ​​to the buttons. For example, as an embodiment, the corresponding functions of the infrared remote control buttons are set as follows: infrared remote control button 1 is for motor reset, and the curtains are closed without changing with the light, that is, the servo is just connected to the electrical angle of 0° as the initialization angle, and the photosensitive circuit acquisition module does not work; infrared remote control button 2 is for opening the curtains, and the fan blades change angle with the change of external light intensity, that is, the photosensitive circuit acquisition module works; infrared remote control button 3 is for the curtains to maintain the status quo; infrared remote control button 4 is for retracting the blinds blades upward; infrared remote control button 5 is for retracting the blinds blades downward.

[0032] For example, in the automatic dimming smart curtain provided in one embodiment, the photoresistor module includes a light intensity acquisition circuit composed of a photoresistor and an analog-to-digital converter, which is used to collect the external ambient light intensity in real time.

[0033] According to the above embodiment, the photoresistor module can automatically complete the opening and closing adjustment function according to the brightness of the surrounding light, so that the user can maintain a comfortable indoor lighting environment when he cannot take care of the opening and closing of the curtains. During the day, the smart curtains will automatically obtain information, and through the control of the single-chip microcomputer, the opening and closing degree of the curtains will be determined according to the indoor light intensity. Specifically, when the external environment is darker, the smart curtains will automatically open to allow more natural light to enter the room; and when the external environment becomes brighter, the smart curtains will automatically close to avoid excessive sunlight from shining into the room, protect indoor items and maintain the comfort of the indoor environment. Through the light control adjustment function, the smart curtains can provide users with a more intelligent and convenient control experience, improving the quality of life and comfort.

Arduino Uno is a development board based on the microcontroller ATmega328P, which has practical features such as multiple digital input / output pins and analog inputs, and can be used in various Internet of Things and embedded system projects. It is simple and easy to use and can be connected to a computer via USB without the need for additional power equipment.

[0035] For example, in the automatic dimming smart curtain provided in one embodiment, the servo rotation angle range is 0-180°. The rotation angle of the servo is achieved by adjusting the duty cycle of the PWM signal. The pulse width of the PWM signal of the servo can be between 0.5ms and 2.5ms, corresponding to the servo rotation angle of 0° to 180°. The present application adopts the servo SG90 9g servo.
