The MPL115A1 is a digital barometer that uses MEMs technology to give accurate pressure measurements between 50kPa and 115kPa. We stock the SPI interface version of the sensor. Average current consumption is 10µA at one measurement per second.
The sensor outputs both temperature and pressure readings on the SPI bus. See page 3 of the datasheet for information on how to take readings from the pressure sensor.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
