Design of wireless sensor system for agricultural Micro environment based on WiFi

摘要

The Implementation of microenvironment monitoring system in network for greenhouse is based on the agricultural greenhouse micro environment and combined with wireless sensor network technology. Information is received by the sensors in the front system with the parameters such as temperature, humidity, light and carbon dioxide. The sensor signal acquisition and A/D conversion is controlled by the processor module which is also the controller of the WiFi wireless module. Wireless router relay communication enlarging the monitoring area is used in the system design. The communication between the terminal nodes and the monitoring center and a series of process like data collecting, processing, transmitting and displaying are all controlled by software. The system has the benefits of networking quick and easy, stable operation, good extension and low power consumption, and it can meet the needs of the micro environment measurement and control system.
