Starbound - Semi-automatic airlock

My new airlock uses drain, sensors and alarms to keep my ocean-floor house nice and dry! This is an evolution of my manual airlock: https://www.youtube.com/watch?v=K-b0QljRoqs The setup is really simple: two liquid sensors switch on two drains and two alarm lights when the water enter the chamber. When the flashlights turn off, I can safely open the lower gate. There's no need to use two drain/sensors/flashlight: I've done it this way just 'cause I like it so.
