I have multiple musical instruments in my room and I thought that it might be useful to know if the temperature and humidity are right for them at any given time. It is known that musical instruments made of precious wood are very sensitive to extreme high and low temperatures, humidities, as well as extreme changes in temperature and humidity. That is why I decided to build my own device that periodically measures the temperature and humidity, and warns if any of those values pose a risk to the valuable instruments.
The code is mostly done. I'm working on the shell and on the permanent wiring.
