The sensor operating mode is user-configurable, allowing selection between different ODRs (down to 1Hz) or the one-shot mode for battery saving. In one-shot mode, the sensor current consumption falls to 1.75µA. Peripheral addresses are also user-configurable, allowing up to four different addresses to be specified by manipulating the jumpers on the back of the breakout. An interrupt pin is available to signal the application whenever the user-selectable high or low threshold has been exceeded.
Connecting the breakout board is easy with the Qwiic Connect System. The board has built-in 2.2kΩ pullup resistors for I2C communications. If multiple I2C devices are hooked up on the same bus, these resistors may need to be disabled.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, reducing the amount of required PCB space. The polarized connections mean that it's impossible to connect it incorrectly.
Features of the SparkFun STTS22H Temperature Sensor include: I2C interface (Qwiic-enabled), four selectable addresses, operating temperature: -40°C to +125°C, temperature accuracy (max): ± 0.5°C (-10°C to +60°C), operating voltage: 1.5V to 3.6V, ultralow current: 1.75µA in one-shot mode, programmable thresholds with interrupt pin, programmable operating modes, and NIST traceability.
