Updated snake environment control system: Physical wiring diagram

Two years ago I built the “Snakeinator 2000” system for controlling temperature, humidity and lighting for my ballpython “Mr. Snuggles”. Currently I’m re-working the wiring and updating the sensors. As part of this effort it made sense to finally documenting the wiring as per the below. This will be supplemented with an update of the code base in the coming weeks.

Note: The 12V power supply / converter I’m using didn’t have a Fritzing model so the one included is a placeholder.
