On behalf of KTH Royal Institute of Technology, Cadson developed both electronics and software for the research project LoTUS (Long-Term Underwater Sensing).
The goal of the project was to develop cost-effective technology for autonomous underwater systems that can collect data from depths where it is usually hard and costly to reach.
The LoTUS-system consists of an underwater buoy with sensors that collect a wide range of data. The electronics is based on Arduino, which makes it easy for the user to adapt it to suit specific needs.
The challenges in this project were related to the huge pressure that the buoy is exposed to at great depths, high demands on the sensors’ precision, and the long time that it remains underwater to collect data.
