Temperatursensor TMP117 ±0.1°C I2C

The TMP117 Precision Temperature Sensor is an I2C temperature sensor that will help you easily add temperature measurement and adjustment to your project. In addition to the obvious support for reading the temperature, the TMP117 can also monitor the temperature and alert you when corrective action needs to be taken.

We use the TMP117 (not N or M) variant, which has 16-bit / 0.0078°C measurement resolution, wide operating range of -55 to 155°C, and up to ±0.1°C accuracy. The chip also has high and low temperature alerts and interrupt support, and hardware support required for NIST traceability, this temperature sensor is perfect for applications where you need to keep a close eye on temperature. The manufacturer, Texas Instruments, suggests it for use in sensitive applications like thermostats and cold chain asset tracking, or even gas and heat meters!

TMP117 temperature sensor has different accuracy for different ranges, here's what you can expect as the maximum variation for popular temperature ranges:

±0.1°C (maximum) from -20°C to +50°C
±0.15°C (maximum) from -40°C to +70°C
±0.2°C (maximum) from -40°C to +100°C
±0.25°C (maximum) from -55°C to +125°C
±0.3°C (maximum) from -55°C to +150°C
