I am wanting to add a pressure switch that will close when my C02 tank pressure gets low to trigger an alarm. I know I can use my ADIN expansion card with a breakout to do it, just wondering if someone else has already done it?

No but I have used the level outlet for doing nearly the same thing - using the function for leakage detection. Just take a level switch and cut of the level indicator. Connect the two wires to your pressure switch and adjust the inverted function in a way that you get an alarm when your CO3 pressure is low.

Here is my use of the adin card in my new aquarium - the thing above was in another application I did.

Sincerely Lasse

Yep that sounds like it would work too but I am already using all of my float switch plugs and I have an empty ADIN breakout. Think I will give it a shot, just need to find a pressure switch...
 

Would you be shocked by today's reefing hobby if you had just returned after a long period of time?
