  • Qwiic Connect System for easy hook-up and I2C communication

The SparkFun STTS22H Temperature Sensor (Qwiic) is a breakout board featuring an ultra-low-power, high-accuracy digital temperature sensor from ST Microelectronics. With factory calibration, the STTS22H provides exceptional accuracy performance over the entire operating temperature range, reaching ±0.5 °C without additional calibration.

The user-configurable operating mode allows selection between various ODRs or one-shot mode for battery conservation. The sensor's peripheral addresses are also user-configurable, supporting up to four different addresses. An interrupt pin signals when user-selectable high or low thresholds are exceeded. The Qwiic Connect System simplifies hook-up, and the board includes 2.2kΩ pull-up resistors for I2C communications.
