This research creates home security service with social interaction based on a web-based multiple stations supervisory control framework. An Arduino controller is used as a thin-controller to control a home security system. Most control laws are computed in server-side, driving commands are transferred to local controllers for execution. A supervisory control server kept in a company can serve numerous Arduino controllers to provide home security service. The Arduino controller can sense door switch, motion detection, smoke detection, gas detection, CO detection, and an emergency button, and can drive door lock, two relays. Besides, RFID is used to help personnel in/out management and alert enable/disable. The controller reads inputs, uploads input/output data to the supervisory server, executes commands from the server, and drives output continuously. Once a controller is connected to the supervisory server, it can be monitored and controlled remotely. Condition control is proposed for the framework to help program control laws for Arduino controllers. In condition control, conditions are set. When some condition is met, certain actions are taken. There are three types of conditions; time condition, input/output condition, and location condition. And there are three kinds of actions; SMS notification, email notification, and output drive. Conditions, actions and their connections are set by system users in a browser with the help of the supervisory control information management system. The control laws set in the condition control are executed in server-side. User of the home security system can open the read/write rights of his input/output points to other users. With appropriate control law, a motion detection signal of one user can activate the alarm of another user. Therefore, the home security service is not just a security for users home, but a security for a social group.
