Flower Greenhouse Environmental Monitoring System Based on Cloud Platform

In order to improve the intelligent level of flower planting, this paper designed a kind of flower greenhouse environmental monitoring system based on cloud platform. The system relies on the STM32 main controller to monitor the internal environmental data of the flower greenhouse through the sensor controlled by the ZigBee node. The monitoring results are sent to the OneNET cloud platform through the WiFi communication module. Users can check the flower environment growth elements anytime, anywhere through the mobile APP. When the environment in the greenhouse is abnormal, the PID algorithm can be used to control the electrical equipment, automatic heating, ventilating, watering, filling light and other operations to adjust the environmental data. when necessary, users can remotely control the operation of the device through mobile phone, thereby promote the improvement of the growth environment of flowers. According to the test results, the system can realize the function of remote monitoring the greenhouse environment.
