We all like to know the temperature, right? Well, with the SparkFun 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 Qwiic connectors to bring this board into our plug-and-play Qwiic 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 TI. While some temperature sensors use an analog voltage to represent the temperature, the TMP102 uses the I2C bus of the single-board computer to communicate the temperature.
The TMP102 is capable of reading temperatures to a resolution of 0.0625°C, and is accurate up to 0.5°C. The breakout has built-in 4.7kΩ pull-up resistors for I2C communications and runs from 1.4V to 3.6V. If you’re hooking up multiple I2C devices on the same bus, you may want to disable/enable the pull-up resistors for one or more boards. I2C communication uses an open drain signaling, so there is no need to use level shifting.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
Note: There is no onboard voltage regulation on this boards. If you choose to provide power via the plated through holes, ensure that your voltage does not exceed the 4V absolute maximum.

3.3V sensor. Supports up to four TMP102 sensors on the I2C bus at a time. 2x Qwiic Connectors
The breakout has built-in 4.7kΩ 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.
The alert pin is an over temperature alert, which has an open-drain and is pulled up through a 10kΩ resistor. The alert can also be read over I2C
