SORACOM Case studies:Safecast

Developing unique devices and creating an open map for radiation data

Safecast was launched in March 2011 following the Great Eastern Japan Earthquake. Using portable sensors, the system automatically polls radiation levels in Japan and around the world and visualizes that data on the Safecast web site. The system now draws on data from sensors installed in homes and other facilities to update data 24 hours a day, 365 days a year.

One major challenging to developing this device was maintaining its simplicity while enabling it to get online even in places with no obvious Internet access. That’s why we chose to use SORACOM Air for its ability to communicate over the mobile grid. This has allowed us to manage the system with minimal installation outlay and have the volunteer groups we work with seamlessly install the sensors themselves. The outstanding User Console has made what used to be various complex services we outsourced separately, a single integrated platform where we can manage devices and SIMs.
