Waves-In-Ice (WII) are custom wave buoys deployed in the Arctic and Antarctic on sea-ice floes. Results from their long-running deployments have been published in Nature.

Gateways

Mon, 01 Jan 0001 00:00:00 +0000

Sh3d builds custom gateways that bridge any device protocol — Bluetooth, LoRa, satellite, proprietary radio — to cloud services, while keeping a full local copy of all data.

Aspect	Detail
Hardware	Low-power, low-cost
Device software	Custom, purpose-built
Protocols	Any: Bluetooth, LoRa, LPWAN, Iridium
Local management	Full local copy of all data

Long-range radios

Sh3d has been using long-range radios for many years across farm, environmental and industrial sensing projects — both plain LoRa and LoRaWAN.

Satellite Communications

Useful for small amounts of data from places nothing else can reach.

Examples

Wave buoys

Antarctic and Arctic wave-buoy telemetry via Iridium — see Waves In Ice.

Farm sensors

Water tanks, weather stations and other remote rural monitoring.

Satellite Trackers

Many tracking systems have been built over the years, including those built into farm equipment and wave buoys. Sh3d also built standalone custom Iridium satellite trackers, used to keep track of multicopters in the harsh conditions of Antarctica.

By being stand-alone and independent from the main systems, these trackers acted as a reliable backup in case of device loss.
