Systems and methods for monitoring a gas sterilization environment

A system for monitoring a gas sterilization process, the system comprising:

• a plurality of sensor assemblies configured to be spaced apart within a sterilization environment, each sensor assembly being associated with a sensor spatial coordinate corresponding to a position of the sensor assembly within the sterilization environment during a first sterilization period, each sensor assembly of the plurality of sensor assemblies including a gas concentration sensor, an environmental sensor, an energy storage device, and a sensor assembly controller, the sensor assembly controller configured to record a plurality of signals from each of the gas concentration sensor and the environmental sensor at a plurality of sampling intervals during the first sterilization period;
• and
• a system controller including at least one processor configured to perform a plurality of operations, the plurality of operations including:
• receiving the recorded plurality of signals from the sensor assembly controller of each sensor assembly of the plurality of sensor assemblies;
• determining a process variable at each sampling interval of the plurality of sampling intervals for each sensor assembly of the plurality of sensor assemblies based, at least in part, on the corresponding recorded plurality of signals;
• generating a spatial distribution of the process variable associated with the first sterilization period based at least in part on the sensor spatial coordinate associated with each sensor assembly of the plurality of sensor assemblies and the process variable at each sampling interval of the plurality of sampling intervals for each sensor assembly of the plurality of sensor assemblies;
• and
• generating an adjustment parameter for adjusting an amount of sterilant gas to be conveyed into the sterilization environment during a second sterilization period based on the spatial distribution of the process variable associated with the first sterilization period and a sterilization process threshold associated with the second sterilization period.
