Cobalt S3, very long-range wireless temperature and humidity monitoring

Wireless data logger equipped with SigFox very long-range technology for tracking temperature and humidity
Continuous monitoring for equipment and warehousing

Ensure quality control for products and manage public health and sanitary risks.

Reduce the risk of degradation, food waste, and financial loss.

Ultra-simple installation with the SigFox network*

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.
