Abstract—In this study, a variety of environmental monitoring, the Arduino sensing value retrieved and transmitted using the XBee wireless signal transmission to the monitoring client computer, information and data are displayed in the interface program Visual C # on; instant catch data sequentially stored in the database. In addition, when sensing value beyond the set threshold is the exception warning, Visual C # displays a warning and sends control signals transmitted to the wireless relay module control electrical appliances to make the switch, improve the environment. For example, when soil moisture deficits, Sprinklers open sprinkler function, to achieve our demands. The future will add another function, when the user is not in the scene, by the application using the Eclipse smartphone over the wireless network, the client computer to connect to the monitor interface program Visual C #, see real-time data, user need not be present also can watch, real data can be viewed through a smartphone, more convenient. This study has several experiments by a number of experimental analysis, combined with Arduino and XBee applied to a variety of situations: Plant care environment monitoring system, can be constructed of a variety of different wireless sensing applications allow users to do by the results of This research further WSN technological development and innovation
