Coastal Monitoring

For a coastal monitoring project here at UH I build and maintain a network of sensors to monitor the water condition around the coasts of the Hawaiian islands.

The sensors measure water level, dissolved oxygen, temperature, salinity, turbidity, pH etc. Some of them are battery-powered; others run on solar power with battery backup and provide real-time telemetry.

The sensors can operate under dense canopy. Data links are typically ISM band or cellular.

Solar-powered real-time water level monitor, from design to deployment.
