It is available to bulk production in all weather all year round, guaranteeing the crop quality. This study used wireless sensor network architecture for multi-monitoring of plant environment, aiming to improve the plant growth environment quality. In terms of monitoring environment, the sensor modules at End Device nodes were combined with Arduino for capturing the sensed values. The sensed values were transmitted by wireless transmission, and the data of wireless signals were transmitted by multiple End Devices XBee to the Coordinator XBee. The Coordinator was in charge of collecting data, which are transferred via Com port to the monitoring-end computer. The system interface classified the sense data, and displayed the sensed values on the screen. The sense data were transferred to Access database for storage. In addition, the sensed values were uploaded to the Cloud hard disk database MySQL, and the real-time environment data were accessed on webpage. In terms of control, whenever an abnormal warning occurred as the environment sensing value exceeds the preset plant growth condition, the system interface displayed a warning, and transfers wireless control signal via wireless sensor network to the control module of end node. The electric apparatus was actuated when the control instruction is received, to improve the environmental quality, until the abnormal warning stopped; then the operation stopped. There was an additional time setting function, the user could set the sprinkling and lighting-up time in the system interface, so that at the preset time, the program sends instruction to the controller to switch on the designated action. According to multi-experimental analysis, the combination of Arduino and XBee was applicable to different situations, such as environmental monitoring system, interaction with situation even robot making. Different wireless sensor applications can be constructed, so that the users can make further WSN technology development and innovation based on the results of this study.
