  4. Prototype • Field Server • Data Logger • Communication • Collect & Display data • Sensors 17th APAN Meeting & Joint Techs Workshop East-West Center, University of Hawaii Honolulu, Hawaii,USA

  5. Field Server Model • 8 channels • Store to Compact Flash (up to 1GB) • Time interval from 10 sec. to 24 hr. • Easy , Cheap • Battery backup 17th APAN Meeting & Joint Techs Workshop East-West Center, University of Hawaii Honolulu, Hawaii,USA

  6. Collect & Display Data • Network • via Wired LAN • via Wireless LAN • via Telephone line • via Mobile communication GPRS • Collect Data to Database • php -> DBMS -> Report • Java -> DBMS -> Report • VB -> Report & Control • Display from Database • Table , Chart , Picture for current / max / min / avg , etc.
