In the hustle and bustle of the city, do you ever yearn for a little green haven of your own? Nowadays, a magical device - the IoT - based miniature plant factory, is quietly making its way into our lives, turning this dream into reality. Today, let's take an in - depth look at the AJ01 Intelligent Automatic Plant Growing Cabinet by Auma. We'll explore how the intelligent control system of this IoT - based miniature plant factory is designed and implemented, and discover the pleasant surprises it brings to our lives.

I. The Birth Background of the Miniature Plant Factory

With the acceleration of urbanization, the distance between people and nature seems to be getting farther. On one hand, the land resources in cities are limited, making it difficult for traditional planting methods to be carried out in a limited space. On the other hand, people's demand for fresh and healthy food is increasing day by day, and the pursuit of a high - quality life also prompts everyone to desire to create a green and environmentally - friendly space around them. At the same time, the rapid development of technology provides a possibility to solve these problems. Technologies such as the Internet of Things (IoT)artificial intelligence, and automated control are gradually maturing, and the miniature plant factory has emerged as the times require. It's like a scaled - down plant kingdom, integrating various advanced technologies into a small cabinet, allowing people to easily plant plants in various places such as homes, schools, and restaurants. While enjoying the fun of planting, people can also harvest fresh and pollution - free agricultural products.

II. AJ01 Intelligent Automatic Plant Growing Cabinet: Functions and Features

(I) Appearance and Structure

The AJ01 Intelligent Automatic Plant Growing Cabinet by Auma has a simple and elegant appearance, with a white main color, giving people a clean and tidy feeling. Its overall size is 140cm×70cm×180cm, and the internal space is reasonably arranged, with a total of 5 layers. Among them, 4 layers are for planting, each layer is 26cm high, and 28 plants can be planted on each layer. The whole machine can plant a total of 112 plants. The other 1 layer is the seedling - raising layer, which is 20cm high and can cultivate 124 seedlings. This integrated design of seedling - raising and planting is very ingenious. It not only saves space but also avoids the cumbersome transplantation process, greatly improving the survival rate of seedlings. It allows us to witness the whole process of plants growing from seeds to seedlings and then to thriving.

(II) Core Functions of the Intelligent Control System

1. Lighting System: Light is one of the key factors for plant growth. The AJ01 plant growing cabinet adopts a built - in light panel design, using three adjustable spectra of red, blue, and white. By simply pressing the manual or automatic switch button, you can easily adjust the power of these three spectra. It uses chips from Jingyuan and San'an in Taiwan, which have many advantages such as high brightness, low heat generation, and precise wavelength. These chips can release quanta suitable for plant photosynthesis, with a natural spectrum color, high display value, no stroboscopic effect, and also have the characteristics of low energy consumption and high light efficiency. Moreover, the lighting system is equipped with functions such as lightning protection, surge short - circuit protection, over - current protection, over - voltage protection, and high - power factor correction, ensuring high safety and stability. Different plants have different requirements for light. For example, leafy vegetables grow faster under a specific ratio of blue and red light, while flowers may need a more diverse spectrum to promote flower bud differentiation and bright colors. The spectrum adjustment function of the plant growing cabinet can meet the growth needs of various plants, allowing each plant to thrive in the most suitable light environment.

2. Temperature and Humidity Control System: Temperature and humidity are also crucial for plant growth. In terms of temperature control, the AJ01 plant growing cabinet can be set according to the needs of different crops, and the temperature control function can be turned on with one click. Its side fresh - air system will send cold/hot air into the planting area, making the cold/hot air distribution more uniform and ensuring that the plants are always in a suitable environment with a balanced temperature. For example, in hot summer, the system will automatically lower the temperature to avoid damage to plants caused by high temperature; in cold winter, it will raise the temperature in time to create a warm growth environment for plants. For humidity control, the humidifier in the plant growing cabinet will create a humid growth environment for plants through the monitoring of precision sensors. Different crops have different humidity requirements. Some tropical plants need a higher humidity, while drought - tolerant plants have relatively lower humidity requirements. The plant growing cabinet can set the most suitable humidity environment according to the characteristics of different crops, effectively preventing the leaves from withering due to drought, promoting the root system to absorb water, and keeping the plants healthy and vigorous. At the same time, the appropriate humidity can also reduce water evaporation, improve the photosynthesis efficiency, and make the plants grow more robust.

3. Carbon Dioxide System: Carbon dioxide is an important raw material for plant photosynthesis. The carbon dioxide system device of the AJ01 plant growing cabinet can accurately set the most suitable carbon dioxide concentration value according to the needs of different crops. When there is sufficient light, providing sufficient carbon dioxide for plants can greatly promote the photosynthesis process, accelerate the growth rate of plants, and increase crop yields. Moreover, a reasonable carbon dioxide concentration can also enhance the disease resistance of plants, making the plants grow more lush. For example, when growing lettuce, appropriately increasing the carbon dioxide concentration can make the lettuce leaves thicker and tastier; when growing flowers, sufficient carbon dioxide can make the flowers bloom larger and more brightly.

4. Automatic Nutrient Solution Fertilization System: The growth of plants relies on various nutrient elements, and the automatic nutrient solution fertilization system of the AJ01 plant growing cabinet is like a "thoughtful butler". Through a peristaltic pump, the nutrient solution is sucked into the mother liquor tank, and then, according to the real - time detection data of sensors, the mother liquor is pumped to the planting trays of each layer in the planting area. This system can increase the concentration of the nutrient solution in real - time and balance the pH value of the nutrient solution. It's like an intelligent nutritionist, which can accurately provide various trace and major nutrient elements for plants, saving the cumbersome manual operation time and ensuring that plants receive sufficient and appropriate nutrients. When growing tomatoes, the system will automatically adjust the proportion of nitrogen, phosphorus, potassium, and other elements in the nutrient solution according to different growth stages of tomatoes, providing strong support for the vigorous growth of tomatoes.

5. Fresh Air System: The fresh air system is like the "respiratory system" of the plant growing cabinet, providing fresh air and a comfortable growth environment for plants. By setting a timing switch, the fresh air system can send fresh air into the planting area at a fixed time, and at the same time, combined with the exhaust function of the air conditioner, the temperature of the entire planting area can be kept balanced. The circulation of internal and external air maintains the balance of oxygen and carbon dioxide, adjusts the temperature and humidity of the environment, and ensures that the environment is always within a suitable range. Fresh air can stimulate the vitality of plants and create a green and healthy planting environment for you. In a closed - type plant growing cabinet, without a fresh air system, plants may grow poorly due to lack of oxygen or excessive carbon dioxide concentration. With the guarantee of the fresh air system, plants can breathe fresh air and grow more vigorously.

(III) Internet of Things and Intelligent Control

The AJ01 plant growing cabinet is equipped with a powerful IoT system. By connecting to remote Wi - Fi, it realizes one - click automatic control of planting. This means that whether you are at home, in the office, or on a trip, as long as your mobile phone is connected to the network, you can control the plant growing cabinet at any time through the mobile phone APP. On the main interface of the APP, both Chinese and English languages are available for selection, which is convenient for different users. Here, you can make various settings, such as time adjustment and environmental parameter setting. The sensor data page will intuitively display all environmental data, allowing you to have a clear understanding of the light, temperature, humidity, carbon dioxide concentration, and other information inside the plant growing cabinet, truly keeping everything under control. Through the policy control function, you can accurately set various environmental parameters according to the growth needs of different plants, achieving precise control of the planting environment from sensors to various gateways. The timing setting function is like a considerate alarm clock, which allows you to provide precise care for plants according to their growth laws. For example, you can set specific times every day to turn on the light and adjust the temperature, enabling plants to grow in the most suitable environment.

III. Design Principles of the IoT - based Intelligent Control System for Miniature Plant Factories

(I) Hardware Design

1. Sensor Module: The AJ01 plant growing cabinet is equipped with a variety of high - precision sensors for real - time collection of various data in the planting environment. The light sensor can accurately measure the light intensity and spectral components, providing a basis for the adjustment of the lighting system. The temperature and humidity sensors monitor the air temperature and humidity respectively to ensure that the temperature and humidity are within the appropriate range. The carbon dioxide sensor is responsible for detecting the carbon dioxide concentration so that carbon dioxide can be replenished in a timely manner. There are also liquid - level sensors, pH sensors, EC sensors, etc., which are used to monitor the water level, acidity and alkalinity, and electrical conductivity of the nutrient solution to ensure the supply and quality of the nutrient solution. These sensors are like the "tentacles" of the plant growing cabinet, constantly sensing the changes in the surrounding environment and transmitting the data to the control system.

2. Controller Module: The controller is the core "brain" of the entire intelligent control system. It receives the data transmitted by the sensors and analyzes and processes them according to preset programs and algorithms. Then, the controller sends instructions to various actuators to achieve precise control of the lighting, temperature and humidity, carbon dioxide, nutrient solution, and other systems. For example, when the temperature sensor detects that the temperature is too high, the controller will command the refrigeration equipment to start and lower the temperature of the planting area. When the light sensor detects that the light intensity is insufficient, the controller will automatically adjust the power of the lighting system to increase the light intensity.

3. Actuator Module: The actuators are the "hands and feet" of the control system, responsible for executing the instructions sent by the controller. In the AJ01 plant growing cabinet, the actuators include the light panels of the lighting system, the air conditioners, humidifiers, and dehumidifiers of the temperature and humidity control system, the carbon dioxide generators of the carbon dioxide system, the peristaltic pumps and valves of the automatic nutrient solution fertilization system, and the fans of the fresh air system. These actuators work together to create an ideal environment suitable for plant growth.

(II) Software Design

1. Data Collection and Processing Software: The data collection software is responsible for real - time acquisition of data from various sensors and preliminary processing and storage of these data. It will perform operations such as filtering and noise reduction on the data to remove abnormal data and ensure the accuracy and reliability of the data. Then, the processed data is stored in the database for subsequent analysis and query. The data analysis software will conduct in - depth mining of the stored data. Through data analysis algorithms, it finds out the relationship between environmental factors and plant growth, providing a basis for optimizing the planting environment. For example, by analyzing the growth rate and quality data of plants under different light intensities, the most suitable light intensity range for the growth of the plant can be determined.

2. Control Algorithm Software: The control algorithm software is the key to realizing intelligent control. According to the preset control objectives and the collected environmental data, it uses advanced control algorithms, such as the PID control algorithm, to calculate the control parameters of each actuator. The PID control algorithm can quickly and accurately adjust the output of the actuator by calculating the proportion (P), integral (I), and derivative (D) of the error, keeping the planting environment in a stable state. For example, in temperature control, when there is a deviation between the actual temperature and the set temperature, the PID control algorithm will automatically adjust the cooling or heating power of the air conditioner according to the size and change trend of the deviation, so that the temperature can return to the set value as soon as possible.

3. User Interface Software: The user interface software provides a convenient and intuitive operation platform for users. Through the mobile phone APP or computer - side software, users can easily control and manage the plant growing cabinet. The user interface software not only has a friendly interactive interface that supports Chinese and English languages but also provides a rich set of functional modules, such as device status display, environmental parameter setting, timing control, and historical data query. Users can perform various operations on the interface according to their needs to achieve intelligent management of the miniature plant factory.
