Detailed ways

The shape of this product is a cuboid, the servo is installed in the middle, and it is fixed. You can move the strut back and forth through the screws next to it to adjust the distance between the rocker arm of the servo and the button handle, and then glue this product to the switch above. After starting up, read the data of each sensor and clock chip and display the time and temperature on the first line of the display, and the second line displays the current switch status and humidity. The open state is displayed as OPHEN, the closed state is displayed as CLOSE, and the humidity is displayed in the form of a percentage. This remote control intelligent switch has two steering gears, one steering gear controls opening and the other steering gear controls closing, and the two work in coordination. If the switch is closed at this time, the opening process is that the right servo first rotates 75° clockwise to raise, and then the left servo rotates 75° clockwise to turn on the switch; the closing process is first rotates the left servo 75° counterclockwise to raise , and then turn the right servo counterclockwise 75° to turn off the switch.

The infrared remote controller has nine buttons: when the remote control's on button and button are pressed, the single chip microcomputer will make the servo turn on or off accordingly and display OPHEN or CLOSE on the second line of the display; when the delay button is pressed The delay time is displayed on the right side of the second line, and the delay time is 30 minutes each time you press it. After the delay is over, the delay display disappears. If it is in the on state, it will be turned off, and if it is in the off state, it will be turned on. Press the end delay button to end the delay and the delay display disappears; when the alarm clock start button is pressed, the delay time is displayed on the right side of the first line, and the delay time is 1 hour each time you press it. After the delay is over, the delay display disappears and the buzzer starts to sound for one minute. Press the alarm clock off button to turn off the alarm clock and the delay display disappears; press the time setting button to set the time, first set the hour, press it again to set the minute, and press it again to set the second. Then press the time plus key or the time minus key on the corresponding time to realize the addition and subtraction of time. The time setting is completed when the time setting key is pressed again.

There are five buttons on the product, which are on-off key, delay key, end-delay key, alarm clock on key, and alarm clock off key. The delay key, the end delay key, the alarm clock on key, and the alarm clock off key are used in the same way as the buttons on the remote control. The on/off key means that the switch is turned on, and then it is turned off, and the switch is turned off, and then it is turned on. The single-chip microcomputer reads the time of the clock module every 0.5 seconds, detects the temperature and humidity every 10 minutes and sends them to the display for display. If the light sensor detects no light, and the sound sensor detects no sound, the display goes out. The display is activated when a sound or a certain light intensity is detected.
