To meet the management requirement of potted flowers, a maneuverable and low-cost wireless monitoring system on the potted flower is designed in this paper. The system includes measuring module, data read and control module, remote wireless communication module and cloud storage module. The Arduino UNO platform is the core control module for this system, and the WiShield module is used as the wireless communication module. And, YL-69, GY-30 and SHT1x sensors constitute the data acquisition module. This system realized the acquisition of the air temperature and humidity, soil humidity and illumination, which were transmitted to the Yeelink platform to be saved or be used for online monitoring by the wireless communication module. This system is easy to be deployed, and has the features of low costs and good scalability.
