Cobalt L3

The Cobalt L3 by OCEASOFT is a wireless device that reads temperature and humidity levels. It uses LoRa™ Alliance technology to achieve a wireless range up to 16 km (10 miles). With its long wireless range, this solution can monitor very large sites easily. Access data via a response-design web application on any mobile device, tablet, or PC with Internet access. Every step in the set-up process is made easy: your parameters are configured using the web application CobaltView and transmitted to your module from the CobaltSet mobile app. You can then access your data stored on OCEACloud using CobaltView
