The base stations also include software which is connected
to the facility’s network and supports data collection functions
including real-time monitoring and scheduled downloads. The
software also allows users to print data and create text files,
tables, and graphs of the data collected by the remote units.
Users can flexibly set sample rates on the data loggers to
measure at frequencies from every second up to every hour for
up to 64 units in one group. The data loggers are set to take a
reading and perform an alarm check every ten minutes
Alarms, alerts, and information retrieval
The wireless base stations also send out automated alarm
emails. Users have configured warning settings so that whenever any of the environmental data goes outside the limits,
email alarms are sent out to all specified addresses. Staff receive
immediate alerts on their mobile devices and pagers which
greatly decreases response times. Up to 50 addresses can receive
these automated alerts.
The wireless base stations transmit all logger data to the
manufacturer’s dedicated Internet server for cloud-based
retrieval. This service lets users remotely access all current
readings and share recorded data from their browsers.
The online service is regularly accessed via smartphone by
an onsite worker who periodically checks it for irregularities.
Additionally, offsite IT support can also access the data in the
Data and compliance
event of emergencies or to zero in on problems. The service
also prevents accidental alteration or deletion of the data by
assigning user IDs.
The facility’s cleanroom integrity benefits in several key ways
following installation of the wireless system. The system’s communication capability spares technicians the trouble of installing
wiring or having to travel to gather the readings manually. The
wireless data loggers help staff maintain the cleanrooms’ differential pressure, temperature, and relative humidity via continual
monitoring and alarming. The data loggers automatically record
all these values and then transmit their measurements to the
wireless base stations in each cleanroom.
Using the base station to aggregate the data, staff can view and
download the real-time numbers anytime from anywhere, and
receive an alert when vital parameters suddenly go out of specification, eliminating delays. Meanwhile, the off-site service keeps all
the online data secure from alteration by unauthorized users.
Due to faster response times and complete data overview,
the facility’s cleanrooms are now fully compliant with USP-797
regulations and the facility has online documentation of its best
practices. The warehouse has since expanded from the initial eight
data loggers to monitor products in adjacent storage rooms.
