“Read the Air”: This year, Safecast is introducing several IoT devices including the Airnote, the Most-Easy-to-Use Air Quality Monitor Ever Built!, and the bGeigie Zen, the exciting follow up to the bGeigie nano, featuring a unique mobile radiation sensor.

This online/offline hybrid event in collaboration with FabCafe Tokyo will be featuring guest speakers Prof. Shigeru Kobayashi (Professor of Institute of Advanced Media Arts and Sciences [IAMAS]), Ray Ozzie (Blues Wireless), Rob Oudendijk (Safecast), Mat Schaffer (Safecast) and Tim Wong (Loftwork and FabCafe Taiwan).




To celebrate Earth Day 2021, Safecast and FabCafe are organizing an online/offline hybrid event featuring several new environmental data tracking IoT devices including the Airnote, the Most-Easy-to-Use Air Quality Monitor Ever Built!, and the bGeigie Zen, the new and improved bGeigie followup to the bGeigie nano which features a unique mobile radiation sensor. Safecast is the leading global Citizen Science project that brings open environmental data collected by volunteers around the world.

The Airnote is an air quality monitoring solution built by Blues Wireless, in partnership with Safecast. Perfect for home, business, and community use, it includes subscription free cellular data across 130 countries, on-device insights, and a complete picture of your environment in a web-based dashboard provided as open data by Safecast. Ray Ozzie, founder of Blues Wireless, will join remotely from Boston, US to talk about the Airnote and the technology that is powering it.

The bGeigie Zen is a mobile radiation sensor based on Safecast original bGeigie. The Zen takes IoT design to the next level by using standard building blocks such as the M5 and a new sensor board, the SafePulse, to build the most cost-effective, easy to build mobile measurement platform. Rob Oudendijk is leading the team designing the bGeigieZen and will talk about how the bGeigie Zen works and what makes it’s design unique.

We will also be joined by Prof. Shigeru Koboyashi, a hero in the world of Arduino/DIY, who will provide his views on where we’re heading with IoT and environmental measurement in Japan and Tim Wong, from Loftwork and FabCafe Taipei, long time Safecast collaborator and creative community builder, who will share with us his insights about these new IoT devices.
