Abstract—Major crisis in human history impose new chal-
lenges to all people affected by it. These great challenges usually
represent a great opportunity for technological development,
since technological solutions are a significant part of the effort
to overcome crisis. The COVID-19 pandemic is no exception to
this historical trend. We present in this work the development
of a technological solution for one challenge imposed by the
corona virus outbreak: disinfection of enclosed spaces. Hence,
the objectives of this work were: 1 - To present some of the
technical choices made to develop the sanitization solution using
UVC light; 2 - To present a methodological framework to adapt
R&D work to the needs of social/physical distance; 3 - To assess
the productivity of the members of the UIoT laboratory during
this remote work period. The solution development was carried
out by a multidisciplinary team and, in order to evaluate the
proposed methodology, a questionnaire was used to assess the
team member’s perception of productivity. Its results show an
overall quality increase, and an individual quantity increase
regarding the project’s outputs. We concluded that the projects’
results were better than what was expected at the beginning of
the year.
I. I NTRODUCTION
Major crisis in human history, caused by wars, extreme
weather or plagues, impose new challenges to all people
affected by it. This challenges may be new in its scales (e.g.
a local drought that cause mass famine) or completely new
(e.g. the first encounter between the Aztecs and the Spanish).
Regardless of its novelty, these great challenges usually repre-
sent a great opportunity for technological development, since
technological solutions are a significant part of the solutions
created during a period of crisis [1]. The COVID-19 pandemic
is no exception to this historical trend. The outbreak caused
by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-
CoV-2) has impacted all aspects of human life in a way not
seen since World War Two [2].
There are many particular challenges presented by the this
pandemic that may benefit from technological solutions, such
as low-cost mechanical ventilators and contact tracing Apps
[3], [4]. Each one of those technologies tackle a specific
sub-problem, patient treatment and virus-spread prevention,
respectively. However, an unique challenge imposed by the
COVID-19 pandemic is the need to social/physical distance, in
order to reduce the spread of the coronavirus. This new daily-
life requirement directly impacts the technology development
process, specially hardware depended technologies. Therefore,
using the previous example, in order to develop a low-cost
mechanical ventilator, a Research and Development (R&D)
team need to adapt its work practices and its technology de-
velopment processes to comply with social/physical distancing
rules [4].
This double-challenge, developing technological solutions
while social/physical distancing, was faced by our team at the
Universal Internet of Things (UIoT) laboratory, of the Uni-
versity of Bras´ ılia (UnB), in Brazil. In the middle of March,
all in-person activities were suspended, what effectively halted
all hardware related projects. At the start of June, some pure-
software solutions were being developed, but no hardware
related group work was being carried out. Thus, we decided to
start a hardware-related IoT project to tackle a issue brought
into the spot-light by the pandemic: disinfection of enclosed
spaces.
The problem of sterilizing and cleaning enclosed spaces
is not a new one. However, it was elevated to a new scale
with the SARS-CoV-2 outbreak, like other similar challenges.
Therefore, the biggest challenge is to adapt the sterilization
and cleaning technology to new uses and make it affordable to
the wider public. A relative low-cost and scalable technology,
ultraviolet type C light (UVC) has been used for more than
100 years [5] in different working conditions. Its well-know
behavior and previous uses in hospitals and laboratories [6],
[7] makes it a natural choice as a solution principle from which
a more affordable and accessible solution can be developed.
Therefore, this work aims to present the development of an
IoT disinfection solution for enclosed spaces and the changes
in work practices and development processes adopted by the
UIoT team in charge of this R&D project. The objectives that
follow this main aim are: 1 - To present some of the technical
choices made to develop the IoT sanitization solution using
UVC light; 2 - To present a methodological framework to
adapt R&D work to the needs of social/physical distance; 3 -
To assess the productivity of the members of the UIoT during
this remote work period.
The remaining of this work is organized as follows: section
II presents some relevant works found in the related litera-
ture. Section III shows the solution’s development process,
describing what was done and how the work was adapted.
A performance assessment of the UIoT team is presented in
section IV, on which a questionnaire was used to obtain the
