Raspberry Pi plot of temperature/humidity/pressure data

Improvements to be made:

  • convert x axis to utc time and make ticks at every hour or every few hours
  • add: light intensity sensor (for sun), rain gauge, wind direction/speed
  • move the temperature sensor out of sunlight to reduce effects from radiant heat, and move it farther away from the window to reduce influence from indoor temperature
  • put pressure on its own axis so it doesn’t need to be divided
  • add units to everything (pressure is in hPa)
  • list everything it took to build my setup


Raspberry Pi 3

MCM Electronics Raspberry Pi 3 Project Kit with GPIO Breakout, Breadboard and Components (On Amazon, which reports it for about $87.99, but it was at Fry’s for $82.99). This is a great starter kit, but is unsupported. The company that made it, MCM Electronics, was apparently bought or merged, and whoever is now in control chose to no longer support the users of this kit, because the starter guide that a piece of paper in the kit refers to doesn’t exist anywhere on MCM’s website (or anywhere on the internet; I searched for at least 20 minutes to no avail).

A great tutorial of how to use the temperature sensors: https://www.jeremymorgan.com/tutorials/raspberry-pi/monitor-room-temperature-raspberry-pi/

Where to find more Raspberry-Pi-like computers: https://www.digikey.com/products/en/development-boards-kits-programmers/evaluation-boards-embedded-mcu-dsp/786. I haven’t looked through it thoroughly, but my brother told me about it. Raspberry Pi seems to be the one that gets the press and is made as a starter kit for beginners, and possibly even started the idea (don’t quote me on that; this is just speculation).
