The PPK-Q030 is a compact digital air pressure sensor module for microcontroller-based measurement projects. Its 0–1500 kPa absolute-pressure range and factory-calibrated sensing design provide digital pressure readings without requiring an analog measurement input.
Select the interface your controller and software support. The I²C and UART options are separate configurations, rather than interchangeable operating modes guaranteed on every module.
Key Features
- 0–1500 kPa absolute air pressure measurement range.
- 2.4–5.5 V operating supply.
- Factory calibration and internal compensation.
- Choice of I²C or UART digital output.
- Compact 24 × 15 mm module footprint.

Model Selection Guide
| Configuration | Interface | Which should you choose? |
|---|---|---|
| I²C — 1500 kPa | I²C clock and data communication | For a controller project using an I²C bus. |
| UART — 1500 kPa | Serial communication at 9600 baud | For a controller project using a UART serial interface. |
Applications
- Microcontroller-based air pressure measurement.
- Pressure sensing and data acquisition projects.
Compatibility & Important Notes
- Absolute pressure uses a vacuum reference; it is different from gauge pressure relative to the surrounding atmosphere.
- Use the communication protocol for the selected configuration. For I²C and UART measurements, acquire temperature before pressure conversion so the internal compensation can use the current temperature.
- The module is a component for integration. Chip pin numbers are not a cable-connector wiring guide; verify the module connector assignments before applying power.
