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.
- Uses the I2C interface
- 12-bit, 0.0625°C resolution
- Typical temperature accuracy of ±0.5°C
- 3.3V sensor
- Supports up to four TMP102 sensors on the I2C bus at a time
