1. Brief description of design
Greenhouse planting monitoring system (OneNet+GPRS communication) designed based on STM32
1.1 Design requirements
With the rapid development of social economy and people's increasing attention to food quality and safety, greenhouses are becoming more and more popular. Greenhouses can provide a good growing environment, allowing vegetables, fruits and other plants to obtain better growing conditions, thereby increasing yield and quality. However, in greenhouses, changes in environmental factors such as temperature, humidity, carbon dioxide content, and light intensity have a great impact on plant growth. Therefore, it is necessary to establish a corresponding monitoring system to monitor these environmental factors in real time for timely adjustment and management.
The currently designed greenhouse planting monitoring system is developed based on the STM32 microcontroller. It can monitor environmental parameters such as temperature, humidity, light intensity, soil moisture, and carbon dioxide content in the greenhouse in real time, and transmit the data to the OneNET cloud platform to achieve remote monitoring and management. The system has the characteristics of small size, low power consumption and high reliability, and is suitable for use in greenhouses and other occasions.
Design intended purpose
(1) Improve agricultural production efficiency
The greenhouse planting monitoring system can monitor the internal environmental parameters of the greenhouse in real time, helping farmers understand the growth status of crops and adjust environmental conditions in a timely manner, thereby improving agricultural production efficiency.
(2) Reduce farming costs
Traditional manual inspection methods consume a lot of manpower and time, but the greenhouse planting monitoring system can automate the monitoring process and reduce farming costs.
(3)
