• 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 a breadboard.
• The TMP102 itself is an easy-to- digital temperature sensor from Texas Instruments. While some temperature sensors an analog voltage to represent the temperature, the TMP102 s the I2C bus of the Arduino 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. I2C communication s an open drain signaling, so there is no need to 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 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.
