Featuring 12-bit resolution and ±0.5°C accuracy, it supports multiple sensors on one bus and operates from 1.4V to 3.6V, making it ideal for Arduino and other single-board computer projects requiring reliable, plug-and-play thermal data. ## Description 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. ## Features - Uses the I2C interface. I2C Address: 0x48 by default (Three additional addresses available, as well). 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. 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B086KZ6RWN | | Best Sellers Rank | #209,369 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #886 in Temperature Probes & Sensors | | Brand Name | SparkFun | | Customer Reviews | 4.3 4.3 out of 5 stars (14) | | Item Dimensions | 27 x 27 x 5 Millimeters | | Item Highlight | Compatible w/ Arduino & other Single-board computers Easy-to-Use I2C sensor Plug-&-Play breakout board Runs 1.4-3.6V input | | Manufacturer | SparkFun Electronics | | Maximum Supply Voltage | 3.6 Volts | | Measurement Accuracy | ±0.5°C | | Model Number | TMP102 | | Number of Items | 1 | | Output Type | Digital | | Part Number | SEN-16304 | | Specific Uses For Product | temperature monitoring | | UPC | 845156010431 | ## Product Details - **Brand:** SparkFun - **Item dimensions L x W x H:** 27 x 27 x 5 Millimeters - **Maximum Supply Voltage:** 3.6 Volts - **Measurement Accuracy:** ±0.5°C - **Output Type:** Digital ## Images ![SparkFun Digital Temperature Sensor - TMP102 (Qwiic) - Use with 3.3V - Image 1](https://m.media-amazon.com/images/I/41RIn35TJML.jpg) ![SparkFun Digital Temperature Sensor - TMP102 (Qwiic) - Use with 3.3V - Image 2](https://m.media-amazon.com/images/I/41h5N55vDkL.jpg) ![SparkFun Digital Temperature Sensor - TMP102 (Qwiic) - Use with 3.3V - Image 3](https://m.media-amazon.com/images/I/4178QpNc9ML.jpg) ![SparkFun Digital Temperature Sensor - TMP102 (Qwiic) - Use with 3.3V - Image 4](https://m.media-amazon.com/images/I/41AWUAmwObL.jpg) ![SparkFun Digital Temperature Sensor - TMP102 (Qwiic) - Use with 3.3V - Image 5](https://m.media-amazon.com/images/I/418jpxJle7L.jpg) ## Frequently Bought Together - SparkFun Digital Temperature Sensor - TMP102 (Qwiic)-Compatible with Arduino and other Single-board computers Easy-to-Use I2C sensor Plug-and-Play breakout board Runs from 1.4-3.6V input Use with 3.3V - I2C Qwiic Cable Kit Stemma QT Wire for SparkFun Development Boards Sensor Board Breakout Breadboard 4 Pin Sh1.0 Connector - SparkFun Qwiic Cable Kit Hook Up I2C Qwiic Development Boards in no time No Soldering Required Includes 10 Different Lengths Styles Breadboardable Polarized 4-pin JST Connector Daisy Chain-able --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/398775668-sparkfun-digital-temperature-sensor-tmp102-qwiic-use-with-3-3v](https://www.desertcart.tn/products/398775668-sparkfun-digital-temperature-sensor-tmp102-qwiic-use-with-3-3v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-06*
