The
HOBO

data
logger
records
carbon
dioxide,
temperature,
and
relative
humidity
(RH)
data
in
indoor
environments
using
non

dispersive
infrared

CO
2
sensor
technology
and
integrated
temperature
and
RH
sensors.
This
Bluetooth®
Low
Energy
‐
enabled
logger
is
designed
for
wireless
communication
with
a
mobile
device
and
also
supports
a
USB
connection.
Using
the
HOBOmobile®

software
on
your
computer,
you
can
easily
configure
the
logger,
read
it
out,
and
view
plotted
data.
The
logger
can
calculate
minimum,
maximum,
average,
and
standard
deviation
statistics
and
can
be
configured
to
trip
audible
or
visual
alarms
at
thresholds
you
specify.
In
addition,
it
supports
burst
logging
in
which
data
is
logged
at
a
different
interval
when
sensor
readings
are
above
or
below
certain
limits.
This
logger
also
has
a
built
‐
in
LCD
screen
to
display
the
current
CO
2
level,
temperature,
RH,
logging
status,
battery
use,
memory
consumption,
and
more.
