Wireless Sensor Networks (WSN) make it possible to develop custom systems which collect various environmental information indoors and outdoors. The sensor nodes can establish communication and construct scalable networks autonomously, simply by placing them in the environment using an ad-hoc network protocol. Therefore they can provide various ubiquitous computing systems based on real environmental information. However, the behavior of each sensor node must be set up according to the application. Thus, advanced programming skill is required for users to develop a ubiquitous environment using WSN. Hence despite its versatility, it is difficult to popularize as a ubiquitous tool for general users. To solve these problems, this research developed a WSN development system using a mobile phone, and examined its effectiveness. It provides a visual programming environment for defining the behavior of each sensor node easily. It is also designed to be accessible to general users.
