Research and Design of Greenhouse Environment Monitoring System Based on NB-IoT

The application of Internet of Things technologies in greenhouses is a crucial method to improve agricultural production efficiency and quality. A greenhouse environment monitoring system is designed based on NB-IoT (Narrowband Internet of Things). The system can detect the air temperature, relative humidity, illuminance, and carbon dioxide concentration in greenhouses in real-time and transmit the data to the OneNET cloud platform in a wireless way. Growers can browse the web page through mobile terminals, such as mobile phone, to observe the greenhouse environment information. The experimental results show that the system can detect the greenhouse environment information accurately and run stably and reliably. The automation level of greenhouse environmental monitoring is improved significantly, which lays a good foundation for the automatic control of greenhouse environment.
