Adafruit_TMP006.h

/***************************************************
  This is a library for the TMP006 Temp Sensor

  Designed specifically to work with the Adafruit TMP006 Breakout
  ----> https://www.adafruit.com/products/1296

  These displays use I2C to communicate, 2 pins are required to
  interface
  Adafruit invests time and resources providing this open source code,
