  Periodic disinfection of workspaces can reduce SARS-CoV-2 transmission. In
many buildings periodic disinfection is performed manually; this has several
disadvantages: it is expensive, limited in the number of times it can be done
over a day, and poses an increased risk to the workers performing the task. To
solve these problems, we developed an automated decontamination system that
uses ultraviolet C (UVC) radiation for disinfection, coupled with occupancy
detection for its safe operation. UVC irradiation is a well-established
technology for the deactivation of a wide range of pathogens. Our proposed
system can deactivate pathogens both on surfaces and in the air. The coupling
with occupancy detection ensures that occupants are never directly exposed to
UVC lights and their potential harmful effects. To help the wider community, we
have shared our complete work as an open-source repository, to be used under
GPL v3.
