Tsunami Detectible Sensors (TDS) in this thesis have developed for detection and distinguish between the long wave length and short wave length in the scale of laboratory. With the main function of these sensors, we can develop and install the portable tsunameters for near real-time detection of tsunami in the ocean environment. The measurement of TDS in the ocean can be provide data to the coastal station for accurate forecasting of tsunami impacts and generate evacuation signal to coastal residential areas. And also, avoid costly false alarms of non-damaging tsunamis. This paper describes four types of sensor that can be developing to TDS in real ocean application. These sensors are pressure sensor, ultrasonic, potentiometer and webcam monitoring. Each sensor has individual transmission unit and display unit in the personal computer. However, for these units are develop and testing in laboratory scale. For further development, the sensors and follower elements should have more specific operating range that compatible with ocean environment scale.
