My standard setup is an Arduino connected to PC either a Raspberry Pi or a nearby PC that can serve as a host.
I decided to relocate my server outside into the garage and I was concerned about how it would cope in the cold and sometimes dusty new environment. My first step was to step up monitoring internally for the server. Disk drive and main board temperatures along with fan speeds would need to be logged. This is covered in detail in my next post.
Once the internal stuff was done I looked at external factors, humidity and temperature being the most important. This is familiar ground for me and setting up a report Arduino was simple as I had a few left from my greenhouses.
With the basics taken care of, I added a sensor to the door to alert if it remained open too long. I also added a check based on the time. The door should be closed between 23:00 and 07:00 most of the time. If it opens between these times I get an alert to my phone to investigate.
I’ll break down each stage in future blog posts.
