How does the Cobalt S3 SigFox temperature sensor work?

  • Almost no installation is required for Cobalt S3 SigFox enabled modules. You’ll be up and running quickly and easily. Cobalt S3 may be equipped with different types of OCEASOFT’s Smart-Sensors, enabling recalibration via our sensor exchange service and facilitating maintenance.
  • Data is stored in module memory and on OCEACloud, which interacts with the responsive CobaltView web application, for remote viewing and management using a smartphone, tablet, or computer.
  • When excursions or other anomalies are detected, you will receive timely alerts 24/7 by e-mail, or by SMS/text message or voice message via the optional OCEAlert platform.
