  1. Data Acquisition with HOBO Wireless Networks Nicholas Lavanda

  2. Introduction • HOBO • Remote Weather Station • Wire-less capability via radio modem

  3. Introduction (Cont.) • Various Sensors • Temperature • Pressure • Relative Humidity • Data Collected • Stored in Logger’s memory • Retrieved by HOBOware software

  4. Problem • Data accessibility limited • Only on computer connected to RF module. • Profile of Data Logger must be on computer to allow interaction • Data display limited • Large text file • HOBOware

  5. Problem (cont.) • Data collected from logger • Stored in text and xml files on computer • Settings can not be edited by 3rd party software • Current System is a bit dated. • Older Equipment • Few sensors

  6. Solution • Data • mySQL database. • Internet • PHP-based website. • Modernizing • New sensors • No go due to budget restraints.

  7. Solution: mySQL Database • Located on satnet server. • Problems with permissions • On Home server for now • Automatically populated by Java program • Date and Time • Sensor Readings

  8. Solution: Website • Primarily HTML and PHP • Data Displayed • List • Graphs

  9. Results • Sample output of Java Code to populate databse.

  10. Results • Filter query on Home Server

  11. Conclusion • Lots of problems with mySQL on satnet. • Only partially working site on satnet • Fully working site on home server.
