Low-cost CTD Instrument - Arduino based CTD for autonomous measurement platform
Jonas Auråen · NORA - Norwegian Open Research Archives · 2019
This thesis describes the development of a low cost CTD instrument intended for use on an Autonomous Survey Vessel (ASV).The vessel will travel at water surface level, stop at regular intervals and release a sensor probe to do water profile measurements along a water column.The probe will primarily measure conductivity temperature and depth, and store these on an internal SD card.The probe is Arduino based and will also have wireless capability for communication while at surface level.The budget constraints of this project requires a low cost alternative of a normally very expensive instrument to be developed.The project is also an attempt at contributing to the efforts of those trying to make CTD instruments orders of magnitude cheaper then professional engineering equipment.V Appendix ....
