Technical overview
- Measures atmospheric pressure (barometric pressure).
- Calculates altitude from the measured pressure value.
- Also measures temperature.
- Provides an I2C interface.
- Provides an SPI interface.
- Is categorized under sensors/modules.
- The sensor's altitude output is primarily suitable for relative changes over short time spans.
- A known reference altitude can be entered as the initial value when absolute altitude is required.
- Long-term measurements may suffer from altitude drift.
- For long-term accurate altitude determination, integrating other sensors such as GPS is recommended.
Notes and version constraints
- The source does not list specific commands, register addresses, or API calls; these must be derived from the datasheet.
- Exact calibration and setting a reference altitude are version-specific and require manual confirmation in the project.
- The source provides no information on power supply, current draw, sampling rate, or accuracy figures; these values must not be invented.
- Certifications, warranty, price, and availability are not mentioned in the source and should not be claimed.
