Guardian wireless monitoring
Guardian is a wireless system for monitoring and logging of environmental data in fish farming: Oxygen, temperature, salinity, turbidity and water currents. The Guardian can be configured with up to three different or identical probes, wholly optional according to what one wants to measure, and at which deep.
Guardian consists of measuring buoys and charging stations and comes with a finished website where you log in to view the measurements, no installation is required. The Guardian byoys can also be reprogrammed with SMS while in function.
Guardian makes it easy to achieve updated information about the environment in the cages. Measurements are sent with GSM to database in the cloud. The program arranges data in different ways and stores statistical information that can be presented by day, week, month, half year or year. The sensors need no calibration or service. The Guardian is equipped with the best in advanced measurement technology, wireless communication and battery technology.
Build your own Guardian as needed, here some examples:
xO2 Guardian: oxygen and temperature
SA Guardian: salinity and temperature
NB Guardian can be supplied with up to three sensors, where you can have the same or different.
