Frequently Asked Questions

What is the difference between absolute and gauge pressure measurement for this sensor?

The LPS22HHTR is an absolute pressure sensor, meaning it measures pressure relative to a perfect vacuum (zero pressure). This is essential for applications like altitude measurement and weather forecasting, where atmospheric pressure is the key variable. In contrast, a gauge pressure sensor measures pressure relative to the ambient atmospheric pressure.

How do I select between the I2C and SPI communication interfaces?

The interface is selected via the sensor's SDO/SA0 pin. Pulling this pin high or low configures the I2C slave address. For SPI mode, the CS (Chip Select) pin must be used to activate the interface. Consult the official STMicroelectronics datasheet for detailed pin configuration and communication protocol timing diagrams to ensure proper integration with your microcontroller.

What is the typical power consumption of the LPS22HHTR sensor?

The LPS22HHTR is designed for low-power operation, typical of STMicroelectronics' MEMS sensors. Exact current consumption figures depend on the selected output data rate (ODR). For the most accurate and up-to-date specifications, including power-down and active mode currents, please refer to the official LPS22HHTR datasheet available from STMicroelectronics.
