Ground Truth Alaska
IoT deployments in Alaska face several challenges: extreme temperatures, wind, months of darkness, freeze-thaw cycles, deep snow pack, corrosion, and curious critters! Infrastructure is thin - the power grid doesn’t cover much of Alaska, and neither do the cell towers.
In collaboration with GTA and Brunner MachineWorks, we designed a low cost wireless extensometer system for landslide instability monitoring. Based on Acconeer 60GHz Pulsed Coherent Radar sensor.
- Instrument in a Jar! Custom Alaska proof enclosure…? so far so good.
- Lithium battery + solar power
- Custom LoRa Mesh protocol for longer battery life and longer distance. (no NOT Meshtastic ;)
- Edge to Cloud solution w/ realtime telemetry
- onboard microSD card for years of telemetry backup
- Multiple backhaul options
- Grid connected WiFi
- Cellular CatM / NbIoT
- Satellite data
Ground Truth Alaska is working on expanding this system at several sites in Alaska.
