How does Cobalt ML3 work?

  • Cobalt ML3 data loggers are fast and easy to install, generally with just single receiver for private networks, and no receiver installation required at all at your site when using public networks (available soon). In addition to an internal temperature sensor, modules may be equipped with an external digital sensor.
  • Data is stored locally 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.
  • Cobalt ML3 modules are geolocated in real-time when connected to a LoRa network.
  • Modules 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. 


The benefits of Cobalt ML3
  • Performance and long-range connectivity on-the-go: Range up to 16 km with the LoRaWan communication protocol (depending on the environment and receiver antenna)
  • Easy to implement and use: adapts to the characteristics of your site
  • Optional waterproof IP67 protection transparent casing for optimal resistance as required in the transport sector (notably regarding cleaning and shocks)
  • Bluetooth Low Energy wireless communication with range up to 50 meters line-of-sight
  • Temperature tracking with the benefit of geolocation information from LoRa network
  • Real-time alarms and alerts by e-mail, SMS/text message, or voice message
