Low power consumption agricultural greenhouse environmental monitoring system design and Implementation

Inhalt:
To ensure the quality of agricultural products, it is essential to monitor crops during planting and growth. In this paper, we develop a Low power consumption agricultural greenhouse environment monitoring system to obtain accurate, realtime, and efficient information on crop growth. With STM32F407, ARM Cortex-M as the core of the acquisition and control unit, the system collects and monitors the temperature, humidity, atmospheric pressure, light intensity and harmful gas index in the growing environment of crops in real-time. The sensor data is transmitted to the server by Narrowband- Internet of Things (NB-IoT) communication technology. We also built a website on the server side to display the corresponding data and control the thresholds remotely. In summary, A real-time crop information monitoring system with long-distance, low power consumption, intellectualization, multi-dimension, and multi-scale is implemented. Users can monitor and control the environment of crops more intuitively by viewing the web interface's text, curve, and picture information. The results show that the system can significantly reduce maintenance costs and simplify operations. The use of this system can effectively improve the economic benefits.
