Unlike most of the other temperature sensors we have, this breakout has a really cool IR sensor from TI that can measure the temperature of an object without touching it.
The TMP007 is the latest thermopile sensor from TI, and is an update of the TMP006.
The internal math engine does all the temperature calculations so its
easier to integrate - you can read the die and target temperatures
directly over I2C. The TMP007 also has better transient management, so
you don't get as much over/undershoot when the temperature changes a
lot.
Simply point the sensor towards what you want to measure
and it will detect the temperature by absorbing IR waves emitted. The
embedded thermopile sensor generates a very very small voltage depending
on how much IR there is, and using some math, that micro voltage can be
used to calculate the temperature. It also takes the measurement over
an area so it can be handy for determining the average temperature of
something.
This sensor comes as a ultra-small 0.5mm pitch BGA,
too hard to solder by hand. So we stuck it on an easy-to-work-with
breakout board. The sensor works with 2.5V to 5V logic so it requires no
logic level shifting. There are two address pins and using a funky
method of connecting the pins you can have up to 8 TMP007's connected to
one i2c bus. We also include a small piece of 0.1" breakaway header so
you can easily solder to and use this sensor on a breadboard. Two
mounting holes make it easy to attach to an enclosure.
