Sensor for certain gases / liquids - how to?

[habuky]

I would like to have a sensor that detects certain gases or liquids.
Given the current possibilities (automation update), can we built that? 

Example: at the bottom of my base, occasionally co2 gathers, depending on the amount of time my dupes stay inside. Now I want to trigger a gas pump that only runs if  CO2 is present.  The trigger should use less energy than a pump running constantly and be reasonable small. 

Any thoughts?

I would like a temperature sensor to measure the fluid inside liquid and gas pipes

Just sift off a small amount from the main line and measure the temp on that before reinserting it.

With a shut-off valve and automation to control it too you could set a timer to allow separate measurements to be done any number of times during a cycle.

This would still lag.

Sure. A bit. But you asked for a method. And in that I presumed you meant something different than the obvious solutions which are; a) accept very slow readings and have a sensor in a one tile hydrogen filled gap across the pipes, or b) cut the line completely, vent everything into a measurement room and pump it out again.

I tried option a but hated the lag.  So instead I use a sensor in the room receiving the gas (base hvac).Still lags.  A direct temp measurement would inspire me to automate the regulators to a set point.  Instead, I control flow

There is another option as well. Control the temperature of the gas/liquid before it is pumped into the pipes in the first place that way there'd be no need for a temp sensor at all.

That is also viable.  I pumped the air to the entropy unit and controlled that temp and then pumped it back.  I hate pumping it twice.  Regulators use same power and can be closer to base.

I am not saying it is a must but a nice to have.  They gave us automation but we need more tools like this suggestion to have a use beyond playing 70's rock songs.

90s rock songs. Thunderstuck was released September 10th 1990.

But honestly. I really don't see a use case that needs temperature sensors for pipes beyond what can already be achieved by the methods described above.

Sorry, 70's rock band

My suggestion for a HVAC would be to create a 'heating' element that is only functional  when the local environment outside it is colder than what you want. Its fairly dumb and straightforward only real problem is when you use a liquid to gas system like I do (my base is hot though so its fine though).

 

It functions by using an automated door to create a vacuum to create an 'off' switch and thermally conductive tiling to conduct the heat to the local environment from a thermally isolated holding cell (abyssalite tiles) for your coolant to the door to the outside. Only caveat is to have a plan to dispose of warmed coolant. With three doors you could probably make a version that flushes the coolant straight into your base. (My version is for cooling my water tanks).
