Here's the greenhouse computer in situ. The air from the fan is now directed across the sensors on the Sense HAT, with the intention of measuring the temperature of the air in the green house, rather than the air in the case that the Pi 3 has warmed up. It's just a balsawood duct, as thats an easy material to cut and glue.
The small case above the main one contains a Pi compatible camera with a fish eye lens and two infra red lights, for night photography.
The program it runs is fairly long, and specific to this hardware combination, but I can add it if anyone asks...
