Digital temperature sensor - STTS22H - Qwiic - SparkFun SEN-21262

Digital temperature sensor equipped with the STTS22H system by STMicroelectronics, which is characterized by high measurement accuracy and low power consumption. The module is factory calibrated and the reading is accurate to ±0.5°C from -10°C to 60°C. The full range of temperature measurement is from -40°C to 125°C . The sensor for communication uses the I2C interface with the default address 0x3C and the possibility of changing it to the address 0x3E, 0x38 or 0x3F using a jumper. The module has three operating modes that are selectable by the user - Freerun, one-shot and Low-ODR.
