Hydroponics Airlock v3

Hydroponics Airlock IC​ code in one IC chip

An environment triggered airlock for those who keep their base at a suitable hydroponics mixture of the three standard gases: O2, CO2, and optionally N2. When the environment is within tolerance the both doors open as a corridor, otherwise it shuts and becomes an airlock. Requires three gas sensors (internal, side A, side B). It allows a small amount of non-standard gases to avoid shutting when using tools or small changes to gas systems. It is designed to support a nice UI using the modular consoles mod if available, an example is in the screenshots.

Note the airlock is specifically designed to protect side A and will allow non-standard gases to flow from A to B in an effort to allow A to be cleaned of toxins This also allows a central base air purifying system that does not need to be co-located with the hydroponics.

Setup

[olist] [*]Set hash's for door type and vent type at top of code [*]Set d0 pin to point to a gas sensor inside the airlock [*]Set d1 pin to point to a diode to show cycle progress [*]Set d2 pin to point to a switch to override the airlock [*]Name vents, doors, and sensors (A side is the hydroponics):

• Vent A (default StructureActiveVent)
• Vent B (default StructureActiveVent)
• Door A (default StructureGlassDoor)
• Door B (default StructureGlassDoor)
• Gas Sensor A
• Gas Sensor B

[*]Optional additions:

• Pressure A (default ModularDeviceLEDdisplay2)
• Pressure B (default ModularDeviceLEDdisplay2)
• Temperature A (default ModularDeviceLEDdisplay2)
• Temperature B (default ModularDeviceLEDdisplay2)
• Toxins (default ModularDeviceLightSmall)

[/olist]

Default environmental conditions

• Pressure within 10% of 85kPa on side B
• Temperature within 0.15% of 298.15K (25C +/- 4.4) on side B
• Ratio of non-standard gases on B <= 0.05% OR Ratio of B < A
