Conrads Switch Box

What the Python Program should do

Scroll pump can stop as soon as turbo pump is in a good range of pressure. Has to be switched on after a while. Individual periodes or pressure. Benefit ->Reduction of hours of operation of the Scroll Pumps

Stop the pump if pressure rises fast due to a broken capton window. Send an alarm.

Store the pressure over time (each minute?).
