The TMP117 is a high-precision, digital temperature sensor. What makes the TMP117 stand out is its ability to be accurate down to ±0.1°C (from -20°C to 50°C). The measurements can also have a resolution of 0.0078°C! This is great for projects that require more stable temperature readings. There are also additional features that come with the TMP117. Some of these features include offsetting the temperature, entering the low-power mode, and averaging the readings.
