SPARKFUN MPL3115A2 Altitude/Pressure Sensor Breakout Board
High-accuracy 20-bit altitude/pressure breakout sensor with I2C interface – ideal for drones, IoT & weather projects.
The SPARKFUN MPL3115A2 Altitude/Pressure Sensor Breakout Board provides high-precision environmental sensing with a range of advanced features for embedded applications. This compact breakout board features the MPL3115A2 MEMs sensor, delivering 20-bit altitude measurement, 20-bit pressure measurement, and 12-bit temperature measurement, with output directly digitised by a high-resolution ADC and transmitted via I2C for easy integration with microcontrollers.
This sensor offers resolution down to 30cm (1ft) for altitude and fractions of a Pascal for pressure, ensuring accurate environmental monitoring. The breakout board includes an onboard low-dropout regulator (LDO), supporting a supply voltage range of 1.95V to 3.6V and a digital interface voltage of 1.6V to 3.6V, making it highly adaptable for low-power and battery-operated projects.
Key features include an autonomous data acquisition mode, a 32-sample FIFO buffer capable of logging data for up to 12 days, and a configurable sample rate from 1 second to 9 hours. The I2C interface (up to 400kHz) ensures fast and reliable communication with minimal wiring. All pins are conveniently exposed via a 0.1-inch pitch header for quick prototyping.
