Space Engineers Tutorial: Event Controller Airlock Explained

This is a redo of the older video with more detail of how the airlock operates, and most importantly, better audio!

I will show you the blocks needed, how to setup the event controller, the logic behind the events, and how to operate manually, using a button, or automating with a sensor. I also create a valve between the air tank and the O2/H2 generator so we don't overfill our system.

Airlock Steps:
Initial State:
Outer door on and open
Inner door closed and off
Airlock vent depressurize on
Event Controller:
Event = Door Opened
Selected Blocks = both inner and outer doors
Select Actions:
Toolbar 1, 2nd slot = inner door toggle on/off
Toolbar 2, 2nd slot = outer door toggle on/off
Toolbar 3, 2nd slot = airlock vent depressurize on/off
Airlock Vent:
Setup Actions:
1st slot = open inner door
2nd slot = open outer door

For all the door controls you can replace the single door with a group of doors or hangar doors to control more complex setups.

Corrections:
6:20 The valve is uni-directional. It will only flow one way, but it will not stop the flow of gas, even when off. So the valve with a connector is still valid. Thank you @sergioruiz1936 for the correction!
