Introduction
The SparkFun Temperature Sensor - STTS22H (Qwiic) and the SparkFun Micro Temperature Sensor - STTS22H (Qwiic) are Qwiic enabled breakout boards based on the ultralow-power, high-accuracy, digital temperature sensor STTS22H from ST Microelectronics. Thanks to its factory calibration the STTS22H offers high-end accuracy performance over the entire operating temperature range, reaching as low as ±0.5 °C without requiring any further calibration at the application level.
