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.

Features:

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
