The sensor's firmware is updated automatically to the latest version when it comes online. All updates to sensor software are posted periodically on our updates page.

Is there a way in the dashboard to view the software version of sensors?

For our software running on the sensor, all sensors run the same software for all customers. You never have to worry about upgrading from one version to another, updates are made automatically. We don’t display the version of our software in the dashboard since they are always on the latest version.
