Solution
The TMP102 sensor is a common digital temperature sensor that uses a standard I
2
C-based
serial protocol.
To make this recipe, you will need:
▪ Breadboard and jumper wires (see
“Prototyping Equipment”
)
▪ Two 4.7 kΩ resistors (see
“Resistors”
)
▪ TMP102 temperature sensor (see
“Integrated Circuits”
)
Wire the TMP102, as shown in
Figure 2-18
.

your device to I

, but watch out: the buses aren't always numbered the same. When
you work with BoneScript, they are numbered
1
and
2
, but if you work from the Linux
command line, they are numbered
0
and
1
. Confusing, huh?
