Development of things in recent years has become one of the major area of the information technology. Wireless networking will bring more benefit for IOT. In this study, we develop a cloud timer system. By the system, we try to develop a RESTful-styled wireless networking framework for IOT. In the system, users may use mobile devices to connect to the timers by wifi connection and then do some setting in order to let the timers connect to the web server. After that, the timers will continue to detect whether the objects passed and send the information to the web server when detected. Although this is a simple application, we hope that by the process we may develop a lower coupling wireless IOT framework system. However, we also hope that this cloud timer system may be helpful in many competition occasions.
