The OpenMetBuoy is an open-source wave-monitoring instrument with Iridium satellite link. The OpenMetBuoy was designed to create impact in many fields such as oceanography and polar science. It makes in-situ data streaming cheaper and more customizable than ever before.
The OpenMetBuoy collects GPS coordinates, movement with six degrees of freedom (6DOF), and temperature data (sensors optional). This data is streamed directly through an Iridium satellite modem.
The user receives data through a Rock7 platform, either by email or through the website GUI. Rock7 charges iridium costs depending on the instrument configuration, see table 3 in publication.
The should be powered by one or more LSH20 SAFT (3.6V D-cell) batteries or equivalent. NOT INCLUDED
Table 1 in the publication might help you decide on the amount of batteries you need.
You can easily configure and modify settings over USB using straightforward Python tools.
A collection of available firmware configurations makes the device ready-to-go.
(The device comes with the steval_gps_waves_drifter firmware).
OpenMetBuoys produced by LABmaker have an electronic carrier board with sockets that carry all breakout boards needed, pull up resistors, space for super capacitors, and a circuit for 8 temperature meters to be connected. A magnetic switch on the board keeps the device turned off during transport, through an outside of the housing magnet.
The carrier board has holes and pads for two D-cell battery holders and extra pads to solder three more batteries in parallel (additional batteries can be soldered to each pad). It fits perfectly in the small RND 455-01082 IP67 enclosure that comes with the product. Other enclosures can be used as well, list of standardized EURO norm boxes.
