Home Smart Planting System Based on Internet of Things

摘要

In view of the fact that most of the home planting information technology level is low, a home smart planting system is designed applying Internet of Things technology. The system uses STM32 microprocessor as the main control chip to design terminal nodes. Each node has the function of sensing the planting environment information such as air temperature and humidity, soil humidity, light intensity, and the control function of drip irrigation and light supplement switch. The number of terminal nodes can be increased or decreased according to the needs, which can meet the basic needs of home smart planting. The terminal node connects the home wireless router through WiFi module, and then transmits the sensing data to the cloud server. The user terminal is a smartphone. User can log in to the home smart planting system through the mobile APP, and then interact with the terminal device, monitor the sensing data in real time, view video of the plant growth status and planting environment, and control the drip irrigation and light supplement devices remotely. The automatic control mode can also be set to control the devices automatically. The system has the advantages of simple architecture, convenient deployment and use. The rented cloud server is used for data storage and data processing. Data is transmitted using the services provided by operators. It is safe and reliable with low operation and maintenance cost, and is suitable for home planting.
