Abstract
Considering the importance of real-time monitoring tropical flower environment parameters, the paper designs a wireless monitoring system based on MSP430F149 for tropical flower growing parameters. The proposed system uses sensor nodes to obtain data of temperature, humidity and light intensity, sink node to collect data from sensor nodes through wireless sensor network, and monitoring center to process data downloaded from the sink node through RS232 serial port. The node hardware platform is composed of a MSP430F149 processor, AM2306 and NHZD10AI sensors used to adopt temperature, humidity and light intensity data, and an nRF905 RF chip used to receive and send data. The node software, operated in IAR Embedded Workbench, adopts C Language to do node data collection and process, wireless transmission and serial port communication. The software of monitoring center develops in VB6.0, which can provide vivid and explicit real-time monitoring platform for flower farmers.
Highlights
Tropical flowers are fine ornamental plants, with broad leaves and colorful flowers, often as the exquisite gift among people
The local monitoring center will analyze, proceed, store, visualize and report data sent from sink node by serial port RS232
The sink node is connected with computers in monitoring center
Summary
Tropical flowers are fine ornamental plants, with broad leaves and colorful flowers, often as the exquisite gift among people. The wireless sensor nodes are deployed in the greenhouse to collect data can cut down the cost in laying electric cables and maintenance, alleviate labor intensity and coordinate data perception, monitoring and collection. This can help technicians better know the conditions in the greenhouse and make wise decision. The wireless monitoring system can collect, process and report the environmental parameters, including temperature, humidity and light intensity in real-time This can help technicians instantly know the growth condition of tropical flowers, which is significant in its effort to ensure safety production, lighten labor intensity and improve efficiency
