The TMP117NAIDRVR is a high-precision temperature sensor from Texas Instruments, capable of measuring temperatures with a typical accuracy of ±0.1°C across the range of -40°C and 100°C with no calibration. 

Here are the board’s main features:

  • High Accuracy and High Resolution. Typical measurement accuracy of ±0.1°C across the range of -40°C and 100°C. The TMP117 also provides a 16-bit temperature result with a resolution of 0.0078°C.
  • Wide Range Supply Voltage. The sensor operates from 1.8 V and 5.5 V at VCC, dispensing the need for voltage regulation. 
  • Low Power Consumption. It has a very low power consumption, typically 3.5 µA, which minimizes the impact of self-heating.
  • I²C Communication. The sensor communicates through the I²C protocol using 0x49 as the default address. By connecting the AD0 Pin to either GND, SDA, or SDL the addresses 0x48, 0x4A, and 0x4B are also available.
