A few years ago I presented a project in which a Raspberry Pi was working as a data logger. A few sensors were connected to this Raspberry, which recorded environmental data such as air temperature, relative humidity, air pressure and the current GPS position. The sensors mostly consisted of ready-made breakout boards that were connected…
