Design of Environmental Monitoring System for Mini Hydroponic Artificial Climate Chamber

Hydroponics mode is very popular in greenhouse leafy vegetable cultivation. According to its requirements for different growth parameters of light intensity, environmental temperature and humidity, and nutrient solution, a miniature artificial climate box hydroponic environment monitoring system is designed, which can be used for home gardening. Or restaurant farm. The system is based on the STM32 controller, which mainly includes an external environment detection module, an external environment adjustment module, a nutrient solution detection module, a nutrient solution adjustment module, an LCD display module and an upper computer display interface. It can monitor the light intensity, temperature and humidity in the miniature artificial climate chamber in real time, as well as the pH value, EC value, DO value and main nutrient ion concentration of the nutrient solution. The relevant actuator works and can automatically adjust various environmental parameters to standard values. The interface displays the changes of various environmental parameters. The system operation test results show that the system can quickly adjust various environmental parameters required for crop growth, and provide stable and reliable environmental conditions for crop growth. At the same time, monitoring the changes in the concentration of the main nutrient segregants obtained will be a follow-up study of crop growth nutrients. The law of absorption provides a basis.
