Abstract
With the increasing attention towards plant growth environments, this paper aims to design and implement a plant growth environment monitoring system based on the STC98C52 microcontroller. This system integrates various sensors and control modules to continuously monitor key environmental parameters for plant growth, including temperature, soil moisture, CO2 concentration, and light intensity. It automatically adjusts heating, cooling, water pumps, fans, and other devices based on measurement results to maintain the most suitable growth conditions. The core control unit of the system utilizes the STC98C52 microcontroller and employs programming to coordinate the collaborative operation of various functional modules.Specific functionalities include:Temperature Control: Utilizing the DS18B20 temperature sensor to monitor environmental temperature, the system automatically triggers heating or cooling mechanisms when the temperature exceeds preset upper and lower limits, accompanied by sound and light alarms, ensuring the stability of the plant growth environment.Soil Moisture Control: Through a soil moisture detection module, the system continuously monitors soil moisture levels. When moisture falls below the set threshold, the system activates the water pump for irrigation and triggers sound and light alarms to maintain appropriate soil moisture levels.CO2 Concentration Control: Employing the SGP30 sensor to measure CO2 concentration, the system engages the fan for ventilation when the concentration surpasses the preset value. Sound and light alarms are activated to maintain suitable CO2 levels.Light Intensity Control: Utilizing a photosensitive resistor to measure light intensity, the system activates supplementary lighting when light levels drop below the set threshold. Sound and light alarms are triggered to ensure sufficient light supply.CO Concentration Control: Utilizing the MQ-7 sensor to monitor CO concentration, the system initiates fan ventilation if the concentration exceeds the set value, along with sound and light alarms, to maintain a healthy plant growth environment.User Interaction and Settings: The system employs buttons for setting upper and lower limits of temperature, humidity, CO2 concentration, and light intensity. Users can manually control the on/off state of heating, cooling, water pumps, fans, and supplementary lighting, as well as switch between different operating modes to meet various plant growth requirements.Data Display: An LCD screen displays real-time measurement values, providing users with intuitive insights into the status and parameters of the plant growth environment.Through this design, the plant growth environment monitoring system effectively provides suitable conditions for plant growth, offering a more stable and optimal environment. The integration of microcontrollers, sensors, and control technology in this system offers valuable insights and references for the development of plant growth environment monitoring domains.
