SUMMARY
Anthurium is known as a famous and precious cut flower in the world, but its growth and ornamental effect is easily affected by environmental conditions such as temperature, humidity and light intensity. An environment parameter monitoring system based on wireless sensor network is proposed to let flower managers understand the status of anthurium growth environment at any time, and take effective measures to improve the environment. The proposed system uses sensor nodes to acquire data of air temperature and humidity, light intensity and soil temperature and humidity, sink node to collect data from sensor nodes through wireless sensor network, and send data to the PC of monitoring center. By using MSP430F149 as the main controller, nRF905 as the communication module, and AM2306, GY-30 and SMTS-II-485X as the air temperature and humidity, light intensity and soil temperature and humidity sensors, the hardware of the wireless sensor network nodes are realized. The node software is developed based on IAR Embedded Workbench and the computer monitoring software by VB6.0. The results show that the proposed system which is accurate and stable can make real-time monitoring of anthurium growth environment in a large scale. Therefore it can be widely applied in agricultural environmental monitoring.
