| Each kind of flowers has a growing environment, so it is very difficult for users to master the best environmental information of all plotted flowers growth.Meanwhile,when the user leaves home, he can’t get the growth environment information of flowers for a long time, so there exist some problems which are unable to remote view data and untimely management in the potted flower management. In order to solve these problems, the wireless sensor network and WiFi technology is applied to the family potted flower management,and the alarm threshold is set in the terminal software according to different environment data of flowers, when the collected data beyond the threshold, the system will send information to the users.The research solution of potted flower monitoring system is firstly discussed in this paper. Introduction the overall design of the system according to the design goals,and the design of hardware and software platform of the system is introduced.The main achievements of this article are as follows:1.The low power sensor terminal acquisition node constituted is designed the microprocessor MSP430F149, wireless radio frequency chip CC2420, temperature and humidity sensor SHT1 X, light intensity sensor GY-30 and soil moisture sensor YL-69, which conforms to the requirements of the system function and performance.2. The design of the gateway node in the wireless sensor network is studied. The Zigbee-WiFi gateway is designed, which uses the Arduino development board as the core and externally connects to the Zigbee and WiFi module through the serial port,and the communication between the Zigbee protocol and WiFi protocol is realized.3. These data are transmitted to the Yeelink platform. The data storage and display can be realized in this platform. Meanwhile, the platform can trigger mechanism of text messages, send alarm information to the user’s phone, which will make users know the information of flowers and simplify the flowers manage.Above all, the potted flowers monitor system can monitor the temperature,humidity and light intensity of potted flowers growing environment accurately and real-time, and users will have more effective management of potted flowers according to these data. |
