FAQ of DS18B20 Temperature Sensor
Q:
Where
physically
on
the
device
does
the
temperature
measurement
take
place?
A:
The
DS18B20
does
not
sense
temperature
directly
through
the
package.
For
all
package
types,
the
DS18B20
senses
temperature
primarily
through
the
GND
pin.
Ensuring
a
good
thermal
connection
between
the
GND
pin
of
the
device
and
the
heat
source
you
wish
to
measure
will
provide
the
best
results.
Q:
Is
there
a
way
to
extend
the
temperature
range
of
the
DS18B20?
A:
No,
there
is
not
a
way
to
increase
the
range
it
reads.
The
DS18B20
reads
with
an
accuracy
of
±0.5°C
from
-10°C
to
+85°C
and
±2°C
accuracy
from
-55°C
to
+125°C.
Q:
Will
a
conformal
coating
affect
the
thermal
response
of
the
DS18B20?
A:
A
thin
conformal
coating
will
not
affect
the
thermal
response
of
the
device.
Q:
Using
OneWireViewer,
can
more
than
one
DS18B20
be
logged?
A:
Yes,
every
DS18B20
will
have
a
file
where
you
can
store
the
data.
Data
will
be
received
from
one
DS18B20
at
a
time.
Q:
Can
you
power
the
DS18B20
from
a
3V
battery?
A:
The
DS18B20
can
be
powered
from
any
source.
Since
batteries
will
dip
in
voltage,
a
nominal
3V
battery
may
not
always
supply
the
minimum
3.0V
the
DS18B20
requires.
We
suggest
a
step-up
voltage
regulator
is
used
to
ensure
the
device
is
supplied
within
its
rated
voltage
range
of
3.0V
to
5.5V.
