Experiment with indoor health sensors in trams

[gonzalocasas]

It would be interesting to experiment with sensors in trams to generate open data to be correlated with other data sets (the data could be transmitted over the public LoRaWAN network.

Outdoor sensors for environmental conditions have been tried already with projects that ran those on top of the trams, so an alternative option would be to try to do some health-related sensing indoors, inside the tram.

There're several options, some are implicit sensing mechanisms, such as:

• Try to detect average feverish conditions, either using a thermal scan, or contact-less surface temperature sensors. The measurement should probably aim for relative values, not precise readings, due to the people dynamics and the potential (in)accuracy of readings.
• Apply some digital signal processing magic to identify bodily noises inside the tram (coughing, sneezing, etc) and estimate flu incidence.

Or alternatively, a more explicit approach:

• Use pulse sensors to explicitly monitor individuals and gather the "pulse of the city" ( @loleg )
