Overview 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 (http://adafru.it/dMS). 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.
PAGE 10
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. © Adafruit Industries https://learn.adafruit.

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.

Pinouts The TMP007 is a very straight-forward sensor, lets go thru all the pins so you can understand what you need to connect to get started (http://adafru.it/dMZ)Power Pins VCC - This is the positive power and logic level pin. It can be 2.2-5.5VDC, so fine for use with 3 or 5V logic. Power VCC with whatever logic level you plan to use on the i2c lines. GND - this is the ground power and logic reference pin. © Adafruit Industries https://learn.adafruit.
PAGE 13
(http://adafru.it/dMZ)I2C Data Pins SCL - this is the I2C clock pin. There's a 10K pull-up already on the board, so connect this directly to the i2c master clock pin on your microcontroller SDA - this is the I2C data pin. There's a 10K pull-up already on the board, so connect this directly to the i2c master data pin on your microcontroller (http://adafru.it/dMZ)Optional Pins These are pins you don't need to connect to unless you want to! Alert - This is the interrupt/alert pin from the TMP007.

Assembly Prepare the header strip: Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - lo ng pins do wn © Adafruit Industries https://learn.adafruit.

Add the breakout board: Place the breakout board over the pins so that the short pins poke through the breakout pads © Adafruit Industries https://learn.adafruit.

And Solder! Be sure to solder all pins for reliable electrical contact. (For tips on soldering, be sure to check out our Guide to Excellent Soldering (http://adafru.it/aTk)).. © Adafruit Industries https://learn.adafruit.

Wiring & Test Arduino Wiring You can easily wire this sensor to any microcontroller, we'll be using an Arduino Connect Vdd to the power supply, 3V or 5V is fine. Use the same voltage that the microcontroller logic is based off of. For most Arduinos, that is 5V Connect GND to common power/data ground Connect the SCL pin to the I2C clock SCL pin on your Arduino.

Download Adafruit_TMP007 To begin reading sensor data, you will need to download Adafruit_TMP007 from our github repository (http://adafru.it/dN6). You can do that by visiting the github repo and manually downloading or, easier, just click this button to download the zip Download Adafruit_TMP007 Library http://adafru.it/dN7 Rename the uncompressed folder Adafruit_TMP007 and check that the Adafruit_TMP007 folder contains Adafruit_TMP007.cpp and Adafruit_TMP007.
PAGE 20
Thats it! Now open up the serial terminal window at 9600 speed to see the temperature in real time. You can try putting your hand or a cold glass of water over the sensor (not touching) to see the thermopile sensor adjust! Library Reference The TMP007 library is pretty straight forward! Start by creating the Adafruit_TMP007 object with: Adafruit_TMP007 tmp007; Or with an i2c address assigned Adafruit_TMP007 tmp007(0x41); // start with a diferent i2c address! Then you can initialize & configure tmp007.
PAGE 21
We suggest the default, 16 samples for best accuracy. begin() will return true or false based on whether it found the sensor, check it using an if statment like so: if (! tmp007.begin()) { Serial.println("No sensor found"); while (1); } Now you can read the Die temperature (the temperature of the physical sensor itself) and Object temperature (the temperature of the stuff in front of the sensor) tmp007.readObjTempC(); tmp007.readDieTempC(); The readings are floating point values, in degrees C.
