The wireless sensor network monitoring of sea level and wind speed

This paper describes about the measurement of sea level using ultrasonic sensor with PVC pipe and wind speed using anemometer for physical oceanography to design the coastal erosion prevention methods. The sensor system installs in the sea and send data to database server on shore via wireless network communication. The controller system using Arduino UNO R3 and Raspberry Pi for data collection and connect to network via Outdoor Access Point. The experimental installs sensor system at light beacon in the sea. The accuracy of sea level about ±0.02 meters and accuracy of wind speed about ±1.08 m/s.
