The front door is held shut by magnetic catch only so it does not form a sealed case for explosive.
That's a great idea for holding the door closed! I've built a drying box but haven't put any sort of door closure on it yet.
My box uses exhaust fans only. Air is drawn in on bottom right side through furnace filters to keep out dust/cat hair etc... It then travels across light bulbs to warm it. The air then rises up on the left, travels to the right over 1st level shelf. It then rises again on the right and travels left over 2nd shelf where it is pulled out of the box through (charcoal air purifier) filters.

The pic is driving two Peltier elements 136Watts each, heat sinks on the outside to cool the hot side.
For a heater i took apart an old hair dryer and took the nichrome coil and modified it to work with my 40Amp 12V power supply (for peltiers and heater).
The microcontroller's job will be just to turn on/off heater and peltier elements untill the humidity inside the cabin get's the lowest and/or maintain it in low levels.
I am still having problems to interface the sensor but i believe i will solve it in a matter of weeks.
