To meet the needs of residents'indoor green plant maintenance,a set of system for intelli-gent maintenance of green plants was designed.Taking STM32 core board as the controller,DHT11 and YL-69 sensors were used to monitor and collect data on the temperature,humidity of the green plant growth environment and soil moisture.The data were transmitted through ESP8266,and delivered to the phone application based on the cloud platform.The system received the command to complete the intelli-gent watering operation.A simple device was built and the test was obtained.The results show that once the soil moisture is beyond the threshold range,the pump automatically watering and the system alarms to alert the user.It can be concluded that the design and device is reasonable and feasible,which can pro-vide a basis for the application of green plant maintenance system.
