## Description

This is a breakout board for the incredibly small TMP102 digital temperature sensor. The TMP102 is a digital sensor (I2C a.k.a. TWI), has a resolution of 0.0625°C, and is accurate up to 0.5°C. This is a very handy sensor that requires a very low-current.

 Communication with the TMP102 is achieved through a two-wire serial interface. There is no on-board voltage regulator, so supplied voltage should be between 1.4 to 3.6VDC. Filtering capacitors and pull-up resistors are included as shown.

**Features:**

- 12-bit, 0.0625°C resolution
- Accuracy: 0.5°C (-25°C to +85°C)
- Low quiescent current 
    - 10µA Active (max)
    - 1µA Shutdown (max)
- 1.4V to 3.6VDC supply range
- Two-wire serial interface
- 2x Mounting Holes
