How does Cobalt L3 work?

  • Cobalt L3 LoRaWAN temperature sensors are fast and easy to install on-site, generally only requiring a single receiver to transmit data. Cobalt L3 may be equipped with several different types of OCEASOFT’s Smart-Sensors, which enables recalibration via our sensor exchange service and simplifies maintenance.
  • Data is stored in data logger memory and on OCEACloud, which interacts with the responsive OCEAView web application , for remote viewing and management using a smartphone, tablet, or computer.
  • Data loggers send an alarm to the server if any excursion or other anomaly occurs, with alerts sent to users via e-mail, or by SMS/text message or voice message 24/7 by the optional OCEAlert platform.
