This is not your typical temperature sensor.
The TMP006 Breakout can measure the temperature of an object without making contact with it.
By using a thermopile to detect and absorb the infrared energy an object is emitting, the TMP006 Breakout can determine how hot or cold the object is.

The TMP006 Breakout has a wide temperature detection range of -40°C to 125°C and an optimal operating voltage of 3.3V to 5V (tolerant up to 7V max).
This breakout works great with most micro controllers connecting via the I2C bus.
