[0082] In another embodiment, the host computer includes a mobile phone, a server, or a PC.

[0083] In more detail, the utility model provides a farm learning device based on Internet of Things control and a farm learning system based on Internet of Things control:

[0084] The farm shape is assembled from basswood boards, which is simple and environmentally friendly. The ESP32 main control board 2 is fixed to the basswood board of the farm through M3 screws and hexagonal copper columns. The sensors and various device modules are locked to the basswood board through M4 screws and nuts.

[0085] The ESP32 main control board 2 in the smart farm has integrated power modules, USB serial port modules, MCU ESP32 circuits and 2.54mm expansion interfaces. It serves as the main control of the entire kit, controlling the sensors and modules combined together. There are two power interfaces on the ESP32 main control board 2. One is a USB interface that can supply power and communicate with the host computer; the other is a DC power interface 23 that supports 7-12V voltage input. The smart farm also provides a 6-AA battery box 18. When the batteries are installed, the DC power interface 23 of the ESP32 main control board 2 provides system power.

[0086] The farm uses a USB data cable to connect the ESP32 main control board 2 to the PC, so that the host computer can communicate with the ESP32 main control board 2 and burn programs.

[0087] The sensor is connected to the ESP32 main control board 2 through a DuPont cable, which is plug-and-play, convenient and fast (the three-wire DuPont cable includes three interfaces: GND, VCC, and S1, and the four-wire DuPont cable includes four interfaces: GND, VCC, S1, and S2, where GND represents the negative pole of the power supply, VCC represents the positive pole of the power supply, and S1 and S2 are signal interfaces.

[0088] (The following 3.3V power supply and 5V power supply are the power supplies on the ESP32 main control board 2)

[0089] The circuit of the ambient light sensor is connected to a 3.3V power supply (because the analog pins of the ESP32 main control board 2 only support 3.3V input), and the signal output pin of the sensor is connected to the analog pin of the ESP32 main control board 2. When the ambient light intensity is brighter, the voltage of the sensor's signal pin is higher. The analog pin of the ESP32 main control board 2 converts the read voltage into a numerical value (0~4095), thereby measuring the ambient light intensity.

[0090] The button module 41 is connected to a 5V power supply (because the digital pins of the ESP32 main control board 2 support 3.3V and 5V inputs), and the signal pin is connected to the digital pins of the ESP32 main control board 2. The button module 41 can only input two states, high level and low level. By judging the high and low levels of the button signal pin, it can be determined whether the button is pressed.

[0091] The water drop sensor 31 is connected to a 3.3V power supply, and the signal pin is connected to an analog pin of the ESP32 main control board 2. The more water the water drop sensor 31 detects, the higher the voltage output by the signal pin. The ESP32 main control board 2 measures the pin voltage and converts it into a numerical value (0~4095) to measure the water volume.

[0092] The human infrared sensor is connected to a 5V power supply, and the signal pin is connected to the digital input of the ESP32 main control board 2. When the sensor detects human activity, it will output a high level through the signal pin, otherwise it will be a low level. The ESP32 main control board 2 uses the signal pin to determine whether there is human activity around.

[0093] The lighting LED 44 is connected to a 5V power supply, and the signal pin is connected to the digital output of the ESP32 main control board 2. The ESP32 main control board 2 sends high and low levels to the lighting LED 44 through the signal pin. A high level turns on the light, and a low level turns off the light.

[0094] The motor 162 is connected to a 5V power supply, and the two signal pins A and B are connected to the digital output of the ESP32 main control board 2. The ESP32 main control module gives a high level to the module A pin and a low level to the B pin to achieve forward rotation, otherwise it is reverse rotation.

[0095] The servo 172 is connected to a 5V power supply, and the signal pin is connected to the digital output of the ESP32 main control board 2. The ESP32 main control board 2 writes a PWM signal to the servo 172. When the servo 172 receives PWM values ​​of different frequencies, it will rotate to the angle corresponding to the PWM.

[0096] The control circuit of relay 152 is connected to 5V, the signal pin is connected to the digital output of ESP32 main control board 2, the switch circuit of relay 152 is connected to water pump 151, the positive pole of water pump 151 is connected to the "COM" pin of relay 152, and the negative pole is grounded. Then the "NO" or "NC" pin of relay 152 is connected to 3.3V in the circuit. When the switch part of relay 152 is opened or closed, the water pump 151 will be turned on and off.

[0097] The LCD1602 display screen 42 circuit is connected to 5V, and the two signal pins correspond to the SDA and SCL of the ESP32 main control board 2 one by one (SDA is the clock line and SCL is the data line). Through I2C communication, byte commands are sent to make the screen display corresponding text and patterns.

[0098] The circuit of the buzzer 43 is connected to 5V, and the signal pin is connected to the digital output pin of ESP32. By sending PWM values ​​of different frequencies, the volume and tone of the buzzer 43 can be controlled.

[0099] The circuit of ultrasonic sensor 37 is connected to 5V, and the two signal pins are connected to the digital input and output pins of ESP32 (the two signal pins are the sending pin and the receiving pin respectively). ESP32 sends ultrasonic waves through the sending pin and receives the reflected ultrasonic waves through the receiving pin, so as to judge the detected distance by judging the time difference between sending and receiving.

[0100] The temperature and humidity sensor 32 circuit is connected to 5V, and the two signal pins correspond to the SDA and SCL of the ESP32 main control board 2 one by one (SDA is the clock line and SCL is the data line). Through I2C communication, byte commands are sent and byte data are read to measure the temperature and humidity of the surrounding environment.

[0101] The positive and negative poles of the solar panel 46 correspond to the colorful self-flashing LED 45 one by one. When the solar panel 46 receives sunlight, the self-flashing LED 45 can emit light by itself. The stronger the sunlight, the brighter the LED.

[0102] ESP32 main control board 2 can also turn on WIFI to communicate with PC and mobile phone, transmit sensor data, or receive instructions from host computer, so as to realize remote monitoring and management.

[0103] It is also worth mentioning that the prior art solutions of the literature generally have the following problems:

[0104] ① Poor scalability. It is difficult to add new sensors or functional modules according to needs, which limits the user's creativity and learning space.

[0105] ② The function is single and can only realize simple environmental parameter monitoring and control functions, and cannot simulate a more realistic farm scene.

[0106] ③ Low integration. The control system of existing solutions is usually composed of multiple independent modules, with complex connections, large space occupation, and inconvenient for users to learn and operate.

[0107] ④ Insufficient communication capabilities. Existing solutions mostly use wired connections, which limits the flexibility of user remote control and data transmission.

[0108] ⑤ The user interaction method is single. The user interaction method of existing solutions is usually limited to simple buttons and indicator lights, which cannot provide intuitive and rich information feedback and operation experience.

[0109] Compared with the existing technical solutions in literature 1, this solution has at least the following advantages:

[0110] ① Comprehensive functions. The utility model integrates multiple sensors, which can realize multiple functions such as lighting control, ambient light sensing, anti-theft alarm, rain detection, temperature and humidity monitoring, soil moisture detection, water level monitoring, relay 152 control irrigation, animal activity monitoring, etc., effectively solving the problem of single function of existing smart farm learning kits.
