I have a Bauer Oceanus that I want to add some monitoring / control circuitry around it. Half for my interest and "because I can", half to add a nitrox stick. I'm all over the electronic side, but seeking some input mainly on hardware.

Want to put pressure and gas sensors on the output, and a SSR control on the input (currently the motor is just on/off at the wall).

So what hardware do I need to tap into HP for the pressure sensor, and then for the gas sensor(s)? What threads should/do I need?

I've found this pressure sensor available in a handful of thread, pressure and electrical specifications. Do I add another Y or T connector in line with my whip Y? DO I replace the Y with a manifold block?
