Another energy monitoring solution using Zeus

We just completed another installation of Zeus (our IoT monitoring/control system)  in a commercial building to collect and report electrical energy consumption.

Zeus - Wattnode

Wattnode device

In this installation, we connected Zeus to a Wattnode Pulse watt-hour transducer (shown above).  The Wattnode Pulse clamps onto the main power line and reads the killiwatts used, converting this data into a pulse output.  Using custom software on Zeus, we were able to read the output from the Wattnode device, format the data, and send it to the cloud via our builtin WiFi radio.  From there, the data can be analyzed, reported, and/or consolidated with other energy data for this particular building.

For a relatively low cost, the owners of this building are now monitoring their energy usage and can take steps to reduce their overall energy usage.

Navdive for research

I’ve been a volunteer diver for a number of years at Maritime Heritage Minnesota (MHM), a marine archeology firm here in the Twin Cities doing underwater survey work in the state,  Over the past few years, we have been working at Lake Minnetonka to search for sunken wrecks and determine what they are and how they got on the bottom.

We’ve used Navdive (our GPS-based navigation system for divers) on many of our survey dives, including yesterday when we spotted a possible wreck on our surface-based side scan sonar in the dive boat.

With Navdive, we were able to:

  1. Preprogram GPS coordinates that were obtained using the side scan sonar on the boat, allowing the diver to navigate to each point while remaining underwater.

2.  Capture GPS coordinates of underwater features that are discovered during the dive for cataloging later.

3. During the post dive analysis, we were able to show the path our divers swam during the entire dive.

The results?  More efficient use of our underwater time, better data for our research, and the ability to integrate all of our data sources (i.e. surface-based side scan sonar, Navdive data, and Google Earth) to produce reports documenting our findings.
