At this point, 12 PiGI - Raspberry Pi Geiger-Müller Interface nodes are in active deployment at TDRM, helping to monitor the environment independently and so far reliably. Additional 12 nodes are on the current roadmap. That is a great success story and just in the spirit of the idea, development and open-source model of it.
Now the TDRM Working Group at Karel-de-Grote Hogeschool, Campus Hoboken in Antwerp pushed it even further and developed a LoRaWan based TTN (The Things Network) Adapter for the PiGI, to have it connected to the Internet of Things:
This project was never intended to generate profit, but to free people from having to rely on government/military based radiation monitoring data. The incidents at Chernobyl and Fukushima showed very clearly how this data is suddenly unavailable or if presented, showing only measurements which can't be trusted, to calm people down.
PiGI was meant to be a cheap, available and easy to replicate solution, serving educational as well as practical monitoring purposes. Something to copy, not encumbered by old “intellectual property” ballast and secrecy. To spread and inspire new developments. Congratulations to the TDRM Working group, for succeeding admirably.
