## Description

Built around Texas Instruments' TMP119, this breakout makes it easy to add extremely accurate temperature monitoring to your project over I2C. It is designed for applications where temperature really matters, including thermostats, cold chain asset tracking, and gas or heat metering, and it can also monitor for out-of-range conditions so your system can take corrective action.Adafruit has mounted the sensor on a breakout PCB in the STEMMA QT form factor, making it simple to use either on a breadboard or with SparkFun Qwiic-compatible STEMMA QT connectors. The board is also designed to work with both 5V systems such as many Arduino boards and 3.3V logic platforms including Raspberry Pi and Feather. A QT cable is not included.If you have used the TMP117 before, the firmware interface is the same here, apart from a different chip identifier so software can tell which device is fitted. Adafruit also provides TMP117/TMP119 support for Arduino, Python and CircuitPython, with wiring guidance, libraries and example code to help you get started quickly.Specifications:Interface: I2CMeasurement resolution: 16-bit / 0.0078°COperating range: -55 to 155°CAccuracy (typical): ±0.03°C from 0°C to 45°CAccuracy (maximum): ±0.08°C from 0°C to 45°CAccuracy (maximum): ±0.09°C from –25°C to 85°CAccuracy (maximum): ±0.12°C from –40°C to 85°CAccuracy (maximum): ±0.15°C from –55°C to 125°CAccuracy (maximum): ±0.2°C from –55°C to 150°CAlert support: High and low temperature alerts and interrupt supportNIST traceability support: Hardware support required for NIST traceabilityFirmware interface: Same as the TMP117, other than the Chip Identifier being differentForm factor: STEMMA QTConnector compatibility: SparkFun qwiic compatible STEMMA QT connectorsLogic compatibility: 5V voltage levels as commonly found on Arduinos, as well as 3.3V logic used by many other boards like the Raspberry Pi or FeathersCable included: QT Cable is not includedA good fit for precision monitoring projects that need easy I2C wiring, broad board compatibility, and ready-to-use software support.
