Measuring and recording the room temperature with a Raspberry Pi

The Raspberry Pi is a small embedded computing device that you can use for many different software and hardware projects. One of the first projects I did with the Pi was turning it into a device that would measure, record and display the room temperature.


To make the project, you will of course need a Raspberry Pi. I use my old Raspberry Pi model B, any newer one would also work. You also need a DS18B20 temperature sensor and a RRU 4K7 resistor. You can buy the separately, or you can buy the Raspberry Pi YouTube Workshop Kit that also contains both parts.

To connect the temperature sensor to the Pi, I suggest you follow the YouTube tutorial for the kit. You can also solder the temperature sensor and the resistor into one piece and connect it to the Pi using this schema, so the result then looks like this

My year with the Raspberry Pi and what I used it for

I have been owning and using a Raspberry Pi for over a year now. I started with Raspberry Pi model B and now I added Raspberry Pi 2 immediately after it was announced. Thanks to the fact that an IoT version of Windows 10 will run on the Pi, there is quite a hype about the Pi 2. Many people who did not care about the Pi before are now buying it because of that hype. And mostly they do not know what to do with it. So here is a list of things I used the Pi for, maybe you can get inspired.

Media center

I always wanted a small cheap low power media center to watch downloaded TV shows on the TV. The Pi was an ideal machine to built. I connected the Pi to a power source, ethernet, external hard drive the TV using HDMI. My distro of choice was RaspBMC at first but then I switched to XBIAN. Using this setup, the PI run XBMC (a media center software), that scanned the connected hard drive, found all the downloaded TV shows, and downloaded their metadata to make the experience better. Thanks to HDMI throughput I was able to control XBMC on the PI using the TV remote, not keyboard or mouse needed.
