We decided to take some measurements of the temperature and humidity in the room before starting to build the fruiting chamber, so that we could know the conditions, and also make sure that our fruiting chamber was not changing the humidity of the basement outside of it too much.
Logan and Anne had an arduino environmental sensor board with an arduino MKR1000 that we could use. There was no wifi in the basement, so we logged the measurements to an SD card.
From a week of measurements we recorded:
min temp: 19.88 °C
max temp: 21.81 °C
min humidity: 61.25%
max humidity: 82.44%
If we want to keep ongoing measurements, it would be nice to get wifi down to the basement somehow.
