The SmartElex TMP102 Digital Temperature Sensor, we’ve made it just about as easy as it gets. Based on the original Digital Temperature Sensor Breakout – TMP102, we’ve added Molex Pico Blade connectors to bring this board into a plug-and-play Ecosystem and added an address jumper instead of breaking out the address pin. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

The TMP102 itself is an easy-to-use digital temperature sensor from Texas Instruments. While some temperature sensors use an analog voltage to represent the temperature, the TMP102 uses the I2C bus of the Arduino to communicate the temperature. The TMP102 is capable of reading temperatures to a resolution of 0.0625ºC and is accurate up to 0.5ºC. The breakout has built-in 4.7k pull-up resistors for I2C communications and runs from 1.4V to 3.6V. I2C communication uses an open drain signaling, so there is no need to use level shifting.


  1. Uses the I2C interface
  2. I2C Address: 0x48 by default (Three additional addresses are available as well)
  3. 12-bit, 0.0625ºC resolution
  4. Typical temperature accuracy of 0.5ºC
  5. 3.3V sensor
  6. Supports up to four TMP102 sensors on the I2C bus at a time
  7. 2x Molex PicoBlade Connectors
