Helium Atom Development Board



The Helium Atom Development Board lives at the heart of your development workflow, allowing you to bring the physical world online. The Atom Development Board contains a Helium Atom Module, two on-board sensors, battery pack, and serial connection for script programming.

When powered, the Development Board will automatically connect to the nearest Helium Element Access Point and report temperature and pressure data, all viewable on the Helium Dashboard.

What can I sense?

Regardless of the asset you need to sense, whether it be machinery or environments – the Helium Development Board* makes building custom sensing solutions ultra-simple.

Your data will be pushed to Helium and visible through our Dashboard, or using our rich API endpoints.

*Requires a Helium Element for full functionality.

System Features
