In order to satisfy peoples demand for realtime information, a new scheme to get sensor observation information on Android phone is proposed which combines with the current development of sensor networks and mobile devices. Based on Android platform, a mobile terminal application is designed and developed to get sensor observation information in real time by interacting with Sensor Observation Service (SOS). Through the application, sensor information and observations which users are interested in can be filtered by time, space and sensor type, and finally displayed on phone. It is proved that this scheme can get sensor information in real time by Android phone and it has feasibility and practicality.
